What is edge rounding with radius 2?


What is radius 2 edge rounding?

The Q-Fin applications, Lian explains. Last time she discussed the most frequently asked questions about removing metal slag. Earlier in this series she discussed the edge rounding of sheet metal parts. This edge rounding can be done with different radiuses, including radius 2. Lian explains what this entails and why it is sometimes necessary. “A radius is a straight line running from the centre of a circle to the edge, half a diameter. When you round off sheet metal parts, you create an edge with a certain radius. Radius 2, also known as R2 or R=2, means a radius of 2 mm.”


Why radius 2?

“Rounding metal sheets has a number of advantages: The product becomes more manageable and safer to work with, therefore work can be done more smoothly, and sharp edges cause poor adhesion of paint or coating, which can flake off and cause rust. Also called corrosion.

How big the radius specifically needs to be differs per application, often this is standardised, for example as P2 or P3. Since, among others, the Dutch government uses radius 2 as a general rule for public installations, this is often used. The question is whether such a steep rounding is really necessary. Does the radius have to be 2 in order to prevent sharp edges and to be able to realise a protective layer on the edges that is as thick and strong as the layer on the rest of the surface? This discussion is particularly important because it takes a lot of effort to reach R2. But is that still the case today?


How to round off with radius 2?

“This can be done in several ways. Firstly, by milling, but that is very expensive. Secondly, the sheet metal parts can be rounded off with abrasive techniques, such as sanding and grinding. This can be done manually or by machine. The manual application of a radius 2 is very labour-intensive and therefore very costly. When machining the edges, many machines require the sheet material to be fed through the machine several times. If this is at all possible due to the shape and contours of the sheet metal.


The Super Edge Rounder

At Q-Fin we thought this could be done better. That is why we developed the SER600, Super Edge Rounder. This machine was designed and built specifically for, as the name suggests, achieving a large edge rounding (R2) on steel. In a single pass, this machine realises a radius of 2 mm on the edges of a sheet or strip. This makes it 5 times faster than similar machines!

Q-Fin specialises in the development, construction and sale of deburring machines and, in addition to the SER600, has developed other specific machines for machining metal sheet parts. Discover our extensive product range!

Edge rounding with radius 2 is just one of the applications that our machines can help you with. In our next blog Lian will tell you all about dust extraction when machining metal parts.

What is metal slag removal?

Lian explains, the Q-Fin applications. Last time, she discussed the most frequently asked questions about finishing sheet metal. Many steps precede this final step in the metalworking process. So does the removal of metal slag. In this blog Lian tells you all about it. What exactly is metal slag? “A metal slag is a stony piece of waste that forms when metals are melted. These metal slag creates differences in height on the products, which gives an undesirable result. That is why these slag is removed.”


How do metal slag form?

“When cutting steel using plasma cutting or gas cutting, slag can form. Melted steel accumulates at the cutting edges of the product. These processing methods are usually used when cutting thicker steel plates. A number of factors influence slag formation. For example, alloys containing a lot of carbon will result in more slag formation. But the material temperature, surface properties and material composition also determine the amount of slag formation.”


Why remove metal slag?

“As indicated earlier, metal slag causes unevenness in metal parts. This does not contribute to the strength and protection of metal, but is rather a form of waste. Also, metal slag does not look attractive or professional. Finally, it makes it difficult to apply an adhesive coating to the surface. Reason enough to remove the slag. But how?”


How to remove metal slag?

“Although metal slag can also be removed manually, with hammer and chisel, this is done less and less often. It is time-consuming and unsafe for the production worker.
Nowadays, more and more machines are available for the removal of metal slag. Special slag remover brushes are used for this purpose. These brushes can be placed in the Q-Fin deburring machines for example, to remove slag quickly and easily. We have also designed a free-standing 600 mm and 1200 mm wide deslagging machine, specially for slag removal. By placing this machine in front of a deburring machine, you prevent the removed slag from ending up in the deburring machine. This is beneficial for the life span of the deburring machine.

At Q-Fin we continue to innovate continuously to create the best machines for you. Discover our extensive range online or drop by our showroom in Bergeijk.

What is finishing?

Lian explains, the Q-Fin applications one by one. Last time she discussed the most frequently asked questions about the edge rounding of metal parts. Another essential application in metalworking is the finishing of metal parts. What is it? And why is it so important? Lian explains.

“By metal finishing we mean the final finishing of the metal parts. In the production of metal, irregularities occur as standard. The finishing of metal makes sure that these irregularities are removed. This can be done in various ways.


Why finishing?

“This final step in the production process of metal parts contributes to the protection and aesthetics of the products. It improves the appearance of the parts and thus their durability. It also makes the parts wear-resistant and corrosion-proof. A smooth surface is easier to clean and requires less maintenance. So it’s ideal for industries where hygiene is a top priority.”


How to finish?

“Finishing metal can be done in various ways. Although it used to be done by hand, for example with a flex-tool, machines are increasingly used nowadays. These automatic machines are set up for your specific requirements. Any desired finish is possible. Also with the finishing machines of Q-Fin. I will now explain a number of possible finishes for you.”


Line finish grinding

“Line finish’ is the most common finish for metal, especially stainless steel. Stainless steel parts with a line grind finish, popularly called ‘brushed’ or ‘satin’, are usually used for visible work: products such as extractor hoods. Surface grinding is usually indicated by a grain size that indicates how finely the surface has been ground. The larger the number, the finer the grit of the grinding belt. For example K320 stands for a 320 grit finish, this means that there are 320 grits on every square centimetre.

Q-Fin machines enable you to give products from 10 mm wide to 1500 mm wide the grinding structure of your choice. A finish with Scotch-Brite or Trizact is also possible. Changing the grinding belt is a snap thanks to the quick-release system.


Grinding without direction

“Directionless grinding is a form of brushed finish for sheet metal work. The term says it all - there is no direction in the grinding structure. This directionless grinding finish is very popular among architects and machine builders. This is because they can use the ground products in all possible directions. It is a finish that is particularly used for stainless steel. Directionless grinding is also known as eccentric grinding, orbital grinding, whirling or quivering. Because the scratches on the product run in all directions, the product is much less susceptible to scratching than a plate polished in line, and can be touched up afterwards.”



“Metal sheet parts can be ground as smooth as a mirror. If a metal product is to have a mirror-like or high-gloss surface, polishing is the way to go. In this process, the surface is first smoothed step by step with progressively finer abrasives. This preliminary process involves grinding to K800. Then the actual polishing begins. Here, practically no material is removed any more, but the surface is “refined” by means of polishing pastes. Visually, a lot changes: the matt finish is transformed into a shiny surface. The surface roughness is increasingly reduced, which has all kinds of technical advantages.


As indicated earlier, Q-Fin specialises in developing, building and selling finishing machines. In our showroom in Bergeijk we would like to demonstrate the possibilities. Come and visit us or discover our extensive range online!

Finishing is just one of the applications that our machines can help you with. In our next blog, Lian will tell you all about removing metal slag.

What is edge rounding?

In 2022 Lian, our Marketeer, explains our applications one by one. Last time she discussed the most frequently asked questions about grinding metal parts. Besides grinding, edge rounding of metal parts is becoming more and more the norm. In this blog Lian tells you all about it. First, what exactly is metal edge rounding? “By edge rounding metal workpieces we provide the sharp edges of these workpieces with a radius. Another word that is often used is edge breaking.”

Why edge rounding?

“Proper and accurate edge rounding is becoming increasingly important in the metal industry. This for several reasons:
- The product becomes more manual and safer to work with. Employees or end users no longer open their hands on sharp edges, so employees can work more smoothly.
- Sharp edges result in poor adhesion of paint or coating, which can flake off and cause corrosion.
- Current standards require a specific predefined radius, making edge rounding essential.”


How to round off?

“There are different ways to round off your metal sheet parts. Before special tools and machines were developed for this purpose, deburring and flap wheels were used. This made edge rounding a time-consuming and inaccurate process.

Today, specific hand tools are available on the market, including milling tools. These tools guarantee a faster and more consistent edge rounding than fully manual tools. However, the quality still depends on the person operating the tool. And the operation is labour-intensive and costly.

There are also several machines available, which apply a constant radius on metal parts in one pass. With maximum GrindingPOWER®, the right combination of power, abrasives and speed, such a machine provides the perfect edge rounding.

Q-Fin is specialized in developing, building and selling machines with maximum GrindingPOWER® that combine deburring, rounding and finishing. This way you not only get a hand-friendly product, but also a product that looks perfect. Discover our extensive product range!


Edge rounding is just one of the applications that our machines can help you with. In our next blog Lian will tell you all about finishing metal parts.

What is grinding?

In 2022 Lian, our Marketer, explains our applications one by one. Last time she discussed the most frequently asked questions about deburring. One way to remove burrs, among other things, is grinding. In this blog Lian will tell you all about it. Starting with: What is grinding? “In short, it is a machining technique that removes material using a grinding belt or abrasive disc. This allows you to remove burrs or unevenness, smooth the surface or apply a certain grinding structure to the material.”


Why grinding?

“If you want to deliver products with a precise and smooth surface, grinding is a must. The smoothness of a surface also determines how much dirt can adhere to it and how easy it is to keep clean and to clean. These are important requirements when it comes to food and health, for example.” In addition, a smooth surface is important for further processing such as welding or bending.

How to grind?

“There is a lot to choose from when grinding metal sheets. Q-Fin has semi-automatic and fully automatic grinding machines in its range. But there are also manually operated machines such as angle grinders. With all these applications, you can choose the grit type and the roughness value to be used for grinding. I will be happy to explain the various options to you.

With which grit should I grind?

“In general, a distinction is made between coarse grit and fine grit. Coarse grit is often used to remove damage, contamination and hard scale from the sheet surface. After this, a surface finish can be considered, for which finer grains or a scotch-brite are used.
In general, coarse grit is used when the surface finish is not essential for the workpiece, when a large surface needs to be machined or when it requires a finishing such as powder coating for steel products. Also called pre-grinding.
Fine grit, on the other hand, is used when the surface finish is essential. For more precise machining of smaller surfaces, lower roughness values and products where the visual aspect plays a role, often stainless steel plate parts, fine grit is also used. This is called regrinding or finishing”.


What is the desired roughness?

“Grinding is possible in several degrees of roughness. Usually, the average roughness, indicated by ‘Ra’, is used. The roughness value after grinding a part is determined by the grit, the grinding speed and the amount of material removal.
The desired roughness can vary per product and material type. For example, as discussed earlier, in the food and health sector it is very important that a product is as smooth as possible.”

What kind of grinding belt(s) should I use?

“There are different types of grinding belts to choose from. For the application we talked about before, the surface grinding of flat sheet metal products, you can use grinding belts with a coarse or fine grain or a scotch-brite belt, as described. But that alone is not enough to make a choice. Various factors play a role in choosing the right grinding belt:
- What material are you going to process?
- What shape is the product to be grinded?
- How will the grinding belt be loaded?
- What base material should the grinding belt consist of?
- Are you going to grind wet or dry?
- Is the grinding belt water-resistant?
We are happy to help you answer these questions.”

Q-Fin specialises in the development, construction and sale of both semi-automatic and fully automatic grinding machines. And that with a speed of at least 3x more than comparable machines. Discover our extensive product range!

Grinding of metal sheet parts is just one of the applications our machines can help you with. In our next blog, Lian will tell you all about rounding metal parts.

What is deburring?

In 2022 Lian, our Marketer, explains our applications one by one. This time she discusses the most frequently asked questions about deburring. Like, what exactly is deburring? Lian is happy to explain: “During the cutting of metal parts, sharp, raised edges or, in other words, burrs, can occur. The removal of these burrs is called deburring.”

Why remove burrs?

“Deburring workpieces has a number of advantages:
- Because the sharp edges are removed, injuries are prevented. It also makes the product more manageable.
- The material looks smoother and more beautiful.
- Dirt is repelled better.
- The material is more resistant to weathering.
- A possible coating will adhere better.
In short, you can’t avoid deburring your products if you want to deliver a high-quality product.”

How to deburr?

“Within the metalworking industry, two mechanical deburring processes are mainly used: manual or mechanical. I am happy to explain both processes to you.”

Manual deburring

“Here you can think of a metal file, angle grinder or Flex machine. The relevant deburring tools can be mounted as required. Manual deburring takes a lot of time and energy, is stressful and unhealthy for the operator and usually does not give a constant finish quality.”

Machine deburring

“Every year the range of deburring machines is extended. The method of deburring can therefore differ greatly from machine to machine and from manufacturer to manufacturer. There are manual, or semi-automatic deburring tables, but also fully automatic deburring machines with conveyor belt.
More and more companies are switching from manual to machine deburring. On the one hand because it is difficult to find labour in the current work climate. On the other hand, because customers demand a constant quality of finish. A deburring machine is also easy to operate and many times faster than deburring by hand. How much faster differs per machine manufacturer. The efficiency goes up, so the investment is earned back quickly.”

Willems Baling Equipment invested in a Q2S double-sided finishing solution, with rotating unit, for its sheet metal parts production.

ISMR says: "A novel feature of the automated deburring line is a rotating unit to automatically turn large workpieces or heavy sheet metal parts."

Dutch deburring machine builder, Q-Fin Quality Finishing Machines, has installed an automatic deburring line at Willems Baling Equipment in Hapert, The Netherlands. A novel feature is a rotating unit to automatically turn batches or heavy sheet metal parts. This enables the parts to be deburred and edge-rounded on both sides in one pass, rapidly and with high finishing quality.
Willems Baling Equipment builds machines for the compressed packaging of bulky products. Typical machine products include bulk handling machines (such as gravel, coil, sand etc.); balers and log shavers. Willems supplies complete production lines to its customers, from production of the raw material to the complete packaging of the product in handy bales ready for sale on a pallet. Engineering, production, assembly, control and service of these production lines are carried out in-house as a total package. Willems values user-friendly operation, sophisticated logistics and maximum safety. Innovation is a key strength, as it continuously works on the development of new machine features and technologies.

Quality in focus
“We want to keep our reputation for high quality so we continuously improve and innovate,” explained Bram Willems, technical sales engineer at Willems, a family business. “We need the best machines to produce efficiently and with high quality. We therefore have a modern machine park, expanded in recent years, with a press brake, a 5-axis milling machine and the Q-Fin deburring line.” A lot of sheet metal parts are needed for the machines that Willems produces, including several large and heavy steel plate parts (up to 25mm thick). This is necessary because considerable force is applied when the products are pressed into bales. A high-quality finish is important for all these parts. “Willems builds to CE quality and no sharp metal edges are allowed. Part deburring is therefore essential. In addition, many parts must be rounded off before electrolytic galvanization and powder coating. All parts of a press installation that are exposed to the open air are, in any case, given a powder coating. By rounding the edges to a radius R1, the paint flows nicely and evenly over the entire sheet metal part. This ensures good adhesion, even at the edges, and prevents peeling and rust", Willems told ISMR.

The search for a solution
Willems already had a deburring machine for deburring and rounding off the large sheet metal parts, which processed the material on one side. Since the sheet metal parts had to be processed on both sides, the material had to be fed through the machine twice and turned in-between. This was done by hand or using an overhead crane, which took a lot of time and was strenuous work for the operators. It was also not one hundred per cent safe. "A crane can slip through the brake and that is dangerous," said Bram Willems. Willems therefore found an alternative solution for processing steel, stainless steel and aluminium parts at Q-Fin Quality Finishing Machines in neighbouring Bergeijk. He was searching for a machine that could process both sides of a part as well as deburr and round-off both sides in one go. However, this concept did not fit Q-Fin's philosophy, as Q-Fin account manager Patrick van Scherpenseel explained. "We like to do things differently. We differentiate ourselves by incorporating the right ratio of power, abrasive and speed into our machines. We call this essential combination 'GrindingPower' and, with it, we achieve the highest output and consistently high quality. This is our starting point and we did not want to dilute it by making concessions," he explained. "However, in a double-sided working machine, you do have to make these concessions. For example, you cannot push as hard with the brushes when working on the product from top and bottom. We therefore looked for a solution that added something to our machines, so that we can still work on both sides of a part in one pass without human intervention. That solution has become the Q2S turnaround unit."

The deburring process
The reversing station is available for two-sided finishing of sheet metal parts up to 600mm, resp. 1200mm and 1500mm wide. The Q2S turnaround station provides batch-wise double-sided finishing at high throughput speeds. The system can be controlled by just one operator. The Q2S1200 turnaround unit is now part of the deburring line at Willems. It is positioned between two F1200 deburring machines. The operator loads the 3m-long and 1200mm-wide table in front of the first machine. He/she enters the correct settings on the control panel on the front machine, which allows him to control the entire system. Sheet metal parts pass through the first deburring machine and are deburred and edge-rounded on one side. They come out the back of the machine and are conveyed straight into the turnaround unit. A sensor registers that all parts are in the reversing unit. The two tables in the turnaround unit are next to each other and a carousel turns them at 180 degrees. All parts are then fed into the second F1200 deburring machine to process the other side of the parts. At Willems, the deburring line is set up so that the operator initiates the turnaround unit. This way, he gives himself time to load the system on one side and unload it on the other. He can work at his own pace and still achieve high throughput.
By choosing two deburring machines and a reversing unit, Willems can now process parts batchwise. “There is a nice flow. This would not have been the case if a rotating unit and one machine had been chosen, into which all the parts would then have had to be fed back. That would mean waiting times,” said van Scherpenseel. “Now, the system works with batches in a continuous process which saves a tremendous amount of time.” The deburring line came with two IOC1200 driven input and output conveyors as well as two WES6000 wet operating extraction systems. The latter are placed on a platform high above the installation so that they take up no space and noise is minimal. Willems also installed an F200 XL machine for the rapid deburring, grinding and rounding of small sheet metal parts and a Skipjoint machine designed for the easy and safe removal of microjoints. Together, these machines form a complete system for deburring and rounding of sheet metal parts, which can be operated by one person. The company is also investing in its future. Due to continued growth, the adjacent plot to its factory in Hapert has now been purchased. The plan is to build a new industrial hall there to create more space for the production and assembly of machines.

Radius measurement after deburring and edge rounding sheet metal parts


Radius measurement after deburring and edge rounding sheet metal parts

Shearing or laser cutting processes for metal parts often leave burr traces on the surface. This is the case with all sheet metal parts for example: steel, stainless steel or aluminium. In order to limit this type of irregularity, several burr standards have been defined by end-users of metal sheets. Additionally, burrs can end up in injuries or entail problems, paint and coating also adhere much better to products with a good radius. For these reasons Q-Fin Quality Finishing has installed a Quelltech radius measurement tool in their laboratory in Bergeijk, The Netherlands.

Q-Fin can now show the exact the amount of edge rounding of the products after deburring and finishing them on their machines to potential customers.

Particular challenges
The size of burrs that their customer are dealing with are in the micrometer range, and some of them may not be discovered by visual inspection. Furthermore, during deburring the metal parts may be subjected to deformation, so their dimensional integrity must be checked as well. For example, a customer needs a R2 (2mm) radius for a good adhesion of the coating.

Q-Fin can now set up their SER600 machine so that the products are finished with a radius of 2mm with a high throughput.

Q-Fin solution with QuellTech Laser Sensor
The robustness of a manual inspection cannot be compared with the speed and the repeatability of a 2D profile inspection by means of a contactless QuellTech Q4 laser scanner. In addition to the verification with respect to burrs and radius, QuellTech decided to fit a circle to the edge to see whether metal sheets still preserve their original form after deburring operation. This means that our inspection covers two tasks at the same time.

Benefits for the client
Thanks to QuellTech’s laser scanner, the customer is able to deliver parts not only in conformity with the edge rounding requirements of the end-user, but also maintaining their original form. Customer using this device can considerably reduce their inspection time and save on labor force.

You can make an appointment at Q-Fin where can they now have the ability to demonstrate that their deburring machines can give the exact radius that is required e.g. a radius R2.

Only 15 candidates left for TechniShow Awards

After an first assessment by the professional jury, 15 exhibitors, including Q-Fin Quality Finishing Machines, have a chance to win one of the TechniShow Innovation Awards. The remaining candidates are all invited to present their innovation during the pitch day on February 11th.

The entries represent the latest trends in the manufacturing industry: digitization, automation, process optimization and solutions for more efficient production. “The expectation prior to the judging was that many entries would have to do with innovations in the pre- and post-processing process. A large number of innovations indeed focus on the pre- and post-processing. Think of online platforms, smart ways of fixation, automation for unmanned production, smart autonomous vehicles for internal logistics and so on. In addition, there were also innovations that monitor the production process and provide more output”, according to the jury. The entries were judged on six points: The extent to which the innovation contributes to smarter and faster entrepreneurship (Smart Industry), the economic impact of the innovation, the commercial added value, the societal impact, the extent to which the innovation is truly new and unique and the quality of the information provided. All in all, the jury was faced with a difficult choice.

This year, the awards will be presented in two categories. The first category is New Tech. These are innovations that were not previously presented at the TechniShow fair and that were introduced to the Dutch market in or after 2019. The second category is Dutch Technology (previously Made in Holland). In this category companies compete, which are originally Dutch and also produce their product in the Netherlands.

Dutch Technology category
Five companies have been nominated in the Dutch Technology category. These are in alphabetical order:

Cellro with the Xcelerate X20|R-C2|6S, a universal solution for automated processing of products on six sides;

ConstruSteel with the software Advanced Scribing for Tekla, with which the ideal marking can be applied to steel profiles and plates from the 3D CAD model;

Kumatech with the AGV vehicles Pallet Jack (pallet truck), Tractor Tom (tractor pallet size) and Dual John (tractor box size);

Leering Hengelo with the APS gantry drill with sub-axles, where the drill axles can carry out a machining operation independently;

Q-Fin with the Q-Fin F600 SP4 containing the combination of a planetary brush system with four counterclockwise/clockwise heads, which also oscillate, resulting in a smooth surface finish and uniform rounding of cut sheet metal.

Announcement of winners
After the pitches, the jury will select the winners in both categories. The winners will be announced during the Evening of the Manufacturing Industry on March 4th. All nominated innovations can be seen at the TechniShow, which will be held from 17 to 20 March in Jaarbeurs Utrecht, Netherlands.

Partnership between Q-Fin and LVD

Partnership between Q-Fin and LVD

Machine builder Q-Fin Quality Finishing Machines from Bergeijk started a cooperation with LVD, the Belgian manufacturer of machines and software for sheet metal working. The LVD sales people will actively offer Q-Fin deburring, edge rounding and finishing machines together with their press brake and laser cutting machines; they will become part of the LVD package.

The cooperation will be visible to the market for the first time during the open days of LVD in Gullegem on 3 untill the 5th of December. An Ultimate Set of Q-Fin (a F1200 deburring and grinding machine for sheet metal parts up to 1200 mm wide, a F200 XL for sheet metal parts from 10 to 200 mm wide and a WES6000 wet-operating extractor) and two table grinders will be demonstrated in the Experience Center of LVD in Gullegem, Belgium. Q-Fin employees will be present for explanations and demonstrations. Before the start of the technology days the first LVD sales employees will have been trained in Bergeijk. The Q-Fin machines will remain permanently in the Experience Center for demonstrations. They are a pilot project. If the experiences with this are positive, the cooperation will be extended outside of Belgium.

Package deals
LVD sales people will be trained on the Q-Fin machines and they will be given a place in the brochures of LVD. “The market is ready for package deals with a laser cutting machine and a grinding machine,” says LVD BeNeLux Managing Director Francis Vanneste. “Especially among customers who want to invest in an efficient cutting process, we see a demand for solutions for rounded and burr-free cutting parts. We are now able to meet this demand in a good way with the Q-Fin machines. We are convinced of the quality of these machines and can sell them flawlessly with our lasers.” Q-Fin’s director/owner Anton Bax also welcomes the partnership: “The fact that a major manufacturer of sheet metal working machines with an excellent reputation in the market and a worldwide sales network will be working with us offers enormous opportunities.

On the Q-Fin stand at the Blechexpo in Stuttgart, LVD CEO Carl Dewulf and Q-Fin director/owner Anton Bax confirmed their cooperation.


Blechexpo Award
The collaboration between LVD and Q-Fin was established shortly before the Blechexpo in Stuttgart. On this international exhibition Q-Fin presented the Super Edge Rounder SER600. This machine won the Blechexpo Award in the Surface Technology category. The jury praised the machine for its speed and the quality of its finish. The winning machine can deburr sheet metal in one pass and round the edges at R2. This can be done at a speed of 1 meter per minute.

Q-Fin at the Blechexpo, 5 till 8 November 2019
In the first week of November Q-Fin was present at the Blechexpo in Stuttgart. The Blechexpo was a great success, not only for Q-Fin itself but also for the exhibition organization which again broke some records. The success of Q-Fin was partly due to winning the Blechexpo award in the surface finishing technology category.

Blechexpo/Schweisstec 2019 with Record-Breaking Dimensions
As expected, the 14th Blechexpo international trade fair for sheet metal working, together with the 7th Schweisstec international trade fair for joining technology, was an industry highlight and closed successfully with 1498 exhibitors from 36 countries. 41,152 visitors from a total of 113 countries took advantage of the trade fair duo, which in the meantime has grown to 108,000 square metres of exhibition floor space, in order to bring themselves up to date with regard to sheet metal, pipe and profile processing, as well as cutting, joining, forming and welding technologies, from the 5th through the 7th of November, 2019.


Blechexpo Awards 2019
Already for the fourth time, the “Blechexpo Award” was presented on the afternoon of the second day of the trade fair by “blechnet” trade journal in cooperation with event promoters P. E. Schall GmbH & Co. KG. The innovation prize was awarded to the most innovative exhibits in five different categories. With its MC 125 automatic stamping press, Schuler was the winner in the stamping and forming technology category. Kjellberg Finsterwalde Plasma und Maschinen won in the cutting technology category with its Q 3000 plasma cutting system. The winner in the joining technology category was Trumpf Laser- und Systemtechnik with their TruLaser Station 7000 – a 3D laser welding machine. The award for surface finishing technology went to Q-Fin Quality Finishing Machines for their SER600 Super Edge Rounder (a deburring and edge rounding machine). Last but not least, Cenit was distinguished in the handling and automation category for their cross-manufacturer cutting and joining software, namely Fastsuite Edition 2.

The Super Edge Rounder from Q-Fin is a machine that deburrs sheet metal in one pass and provides the part with an edge rounding of R2, at a speed of 1 meter per minute. The SER600 is about twice as long as the regular F600 deburring machine in the Q-Fin range. This machine was specially developed for a radius 2 mm on steel products by means of five machining stations in the machine. The secret is mainly in the brushing principle, the way of brushing. The first two rows of brushes apply pressure from above. Brushes three and four work on the sides, the combination ensures the perfect rounding of 2 mm on a product.

Metaalcenter Driessen B.V. up-to-date

Metaalcenter Driessen located in Weert is one of the Q-Fin users from the very beginning. After 4 years of loyal service, owner Antal Driessen thought it was time to switch his machines for the latest versions. The Q-Fin deburring machines are the machines with which he can save the most money, says Antal. He is so enthusiastic about it that he even wrote a blog about it:

Today the big changeover trick took place at Metaalcenter Driessen B.V.

The company Q-Fin B.V. came to replace our old grinding/rounding machines and wet extractors with new ones.

An F200 XL was replaced by a new version of the F200 XL with some new options and of course the new “look”. This machine is only used for laser-cut products from stainless steel and aluminium to provide rounded cutting edges and a re-grinded surface. This machine is equipped with a vacuum system, so that the stainless steel and aluminium products remain perfectly fixated on the conveyor belt during the processing.

An F200 was replaced by a new F600 also with the new look. This machine is only used to provide laser-cut steel products with rounded cutting edges and a re-grinded surface (directionless brushing). This machine is equipped with a magnetic support system, so that the steel products remain perfectly on the conveyor belt during processing.

A bit of training in operating convenience and maintenance is of course also part of the job. Through this training we have been refreshed and updated to take account of the new possibilities. We are ready for it again! As of tomorrow we are back in full production!

Dust-free grinding for a healthy working environment is certainly not new to us. However, also the extraction we had for the two “old” sanders, have now been replaced by a new extraction with double capacity. Of course, this extraction is only activated during the grinding process.

The suction is switched on automatically during the deburring process. This makes the operation both energy efficient and healthy for our working environment.

All in all a beautiful set to look at and a pleasure to work with!

By supplying your products in a user-friendly manner, these too will become a pleasure to work with within your organisation.

Also, a “lace rounding” ensures a better adhesion of a lacquer or coating. This in combination with our oxide skin free products (steel up to 12mm oxide skin free), the perfect solution for a tightly lacquered result!

Q-Fin installs first three Super Edge Rounder machines

Radius 2 rounding on cut parts in one pass: 3x SER600 operational

In June, Q-Fin installed the first three SER600 machines at customers. They had already been sold before the company in Bergeijk had built them. A sign that there is a great need for this deburring machine that can grind a Radius 2 in one pass on sheet metal parts up to 600 mm wide. This was already evident at the end of last year when Q-Fin announced the launch of this machine in the form of a large number of reactions.

“The market is really waiting for it”, we hear from Product Manager Joost Kouwenbergh of Q-Fin. “Especially the steel processors with thicker laser, plasma and oxyfuel cut products that need to be galvanized and/or powder coated. They are increasingly confronted with R=2 rounding standard, for example in constructions for the government, but also in the petrochemical industry. With the SER600 we are responding to this. We did not modify an existing machine, but developed and built this machine solely to be able to get a Radius 2 on steel. Less is also possible, a R=1 or R=1,5 is in many cases sufficient, but R=2 now also can be achieved.”

“A Radius 2 means optimal edging coverage”, explains service engineer Erik Cox. “The rounding is such that a layer of lacquer or zinc on the corners is just as adhesive as elsewhere on the product. This prevents oxidation. Corrosion always means extra maintenance costs. And it can also be dangerous because it can affect the stability of a product. Just think of bridge parts that are not in sight. If corrosion can occur there for an unseen length of time, it can eventually weaken the bridge.”

Q-Fin is not the only one in the market who claims an R=2. Yet this machine is unique, says Erik. “The crux is the combination of 2 different brushing techniques. This allows it to reach R=2 in one passage at 1 meter per minute. Other machines can’t do that. That makes a big difference in production speed, while the quality is constant.”

High emergency’ with prototype compensated
Jos van den Besselaar Constructie in Udenhout, Van der Sluis Technische Bedrijven in Genemuiden and Staalservice Zuidbroek in Zuidbroek are the first companies which have purchased an SER600. “One of these customers even had such a ‘high need’,” says Joost, “that we have already completed a large series of products with our prototype machine in Bergeijk for them. In this way, we were able to help the customer move forward without already having the machine in place. Normally at Q-Fin we deliver the machines with 2-3 weeks delivery time, but the first three still had to be built, while the demand was already there. So that took a little longer in this case. In the meantime, we have the following three machines under construction, for which there is already a great deal of interest.”

Operators can easily set up their own machine
Erik is responsible for the installation of the SER600, often together with a wet-acting extractor and associated piping. “Including a training for the operators, this will take about a day,” he says. “The installation is similar to that of other Q-Fin machines, only the SER600 has five instead of three machining stations. This makes the machine a lot longer and the explanation takes a little more time. What is the same is its simplicity and ease of use. Operators can work with it immediately after training and can also set up and adjust the machine themselves. They don’t have to wait for a workshop manager or foreman to arrive or something like that. They also get the instructions as a manual and we watch when they finish their first products. We really help the operators on their way.” At Q-Fin, they have service for the customer, who they prefer to call ‘partner’. The installation therefore includes aftercare. “We always come by after a few weeks, or earlier if desired, to answer questions, to do things, to help a new operator move forward, whatever is needed. And in between, you can always call. That’s what we’re for,” says Erik. “Customers are always welcome to join the QKC (Q-Fin Knowledge Club) every Wednesday afternoon in Bergeijk”, adds Joost. There they can ask questions and they can also bring their own products to finish on our machines. It doesn’t matter which machine they have and whether it’s just two weeks old or two years old. Just give us a call and we’ll take care of it.”

Why not earlier?
The best part of the installation work comes at the end, says Erik. “These are the reactions of the operators when they see the results. They really appreciate the clean, consistent quality, even at the smallest recesses, and the great speed. Especially when they come out of a manual situation, that’s a world of difference. On average, our machines then go four or five times faster. And don’t forget other aspects. Working with a handheld machine, for example, puts a lot of dust, noise and vibrations on your hands, so that’s another area where the operators benefit enormously. It is also difficult to find people who are willing to do this work. The most frequently heard comment is: “Why haven’t we bought such a machine before?”

Joost nods: “ You get immediately used to the quality and speed. Then you can’t go back. It’s like switching to a faster computer. After an hour you are so used to it that the old situation in which you might have been for years is no longer conceivable. Customers don’t want without the machines anymore.”

The reactions during the installation of the first SER600 machines were also extremely positive, says Joost. At a customer he even saves 4 men. They are now doing the same deburring work with 1 man instead of 5. “We expect the same tenor from the next customers who have already registered”.

Radius 2 in one pass

Q-Fin Quality Finishing Machines introduces the new SER600 Super Edge Rounder. This machine is specially designed to apply a 2 mm radius on steel in one pass, with a speed of 1 M/MIN.

There is a lot to do about a 2 mm edge rounding (r = 2 mm). The question is whether such a substantial rounding is really necessary to prevent sharp edges, or more important to apply a protective layer (for example, when powder coating or galvanizing) on ​​the sides, which is as thick and strong as the layer on the rest of the part. This discussion is particularly important because it requires a lot of effort to get a R2. A lot of material must be machined; for R2 about a hundred times more as for R0.2. Nonetheless, the central government uses Radius 2 as standard for public installations in which sheet metal is used as a general rule. This edge rounding must therefore be achieved. This can be done by milling, but this is very expensive. The material can also be removed by abrasive techniques (sanding and grinding), both manually and mechanically. The manual application of a radius of 2 mm to is very labour-intensive and therefore increases the cost price. In case of rounding the products with a deburring machine, the material has to be run through the machine several times before reaching a R2 rounding. In many cases it is not even possible due to the shape of the product or characteristics of the machine.

Specifically built for R2

Q-Fin introduces the SER600 that can apply a 2 mm radius on steel in one pass. "This is not a standard machine that can also give a large edge rounding, but a machine that is specifically built to put a R2 on steel", emphasizes Joost Kouwenbergh, Product Manager at the machine builder in Bergeijk. "If you want extreme finish results, you need to do something special. That is why we have developed this unique machine. "

The SER600 has a considerable size. It is about twice as long as the regular F600 deburring machine in the Q-Fin range. This is because the machine has five workstations: one grinding belt upfront followed by four brush units. The uniqueness is mainly in the brush principle, the way of brushing. Kouwenbergh explains: "The first two brush units give pressure from above. Brushes three and four work the sides". The combination ensures a perfect rounding of 2 mm on the product.

The SER600 with magnetic conveyor belt is suitable for working steel sheet metal parts up to 600 mm wide, with a material thickness of 4 up to 150 mm. The length of the products is unlimited. The Super Edge Rounder machine is an important addition on the current machine program for Q-Fin. "Our finish options were already comprehensive, but R2 in one go was not possible yet. Now we can achieve that. "According to Kouwenbergh, there is definitely a need for this machine in the market. "Of course it is a niche market. Those who work with thin stainless steel sheet metal parts do not need this machine, but a construction company who is involved in the production of public installations on behalf of the government or parts for the petrochemical industry does. For products that need to be powder coated or galvanized, this machine is ideal and that's why we have high expectations. The first response of potential customers is very enthusiastic”.




Q-Fin winner EuroBlech Award E-Mobility


Q-Fin Quality Finishing Machines has won the EuroBlech 2018 Award in the E-Mobility category. The Dutch company received the award officially at the EuroBlech trade fair in Hanover.

E-Mobility is the category that focuses specifically on lightweight and component design. Q-Fin won this price by entering their F200 XL in the competition. This machine was developed with the vision 'think small, go big' and is for deburring, grinding and finishing of (very) small sheet metal products like laser cut parts (from 15 × 15 mm up to 200 mm wide).


Q-fin scores with new design

"Super". Anton Bax, director-owner of Q-Fin Quality Finishing only needs one word to describe the way in which the new design of his machines for deburring, grinding and rounding of cut flat sheet results has been received by the market. "Everyone finds the new look progressive. We have set a new standard."

The new machines (model year 2018) had their Dutch premiere at METAVAK in Gorinchem and the European introduction was a week later at the Blechexpo in Stuttgart. At both fairs the models were an eye-catching appearance.


Inspired by mobile phone
First of all because of their outer shape. The new Q-Fin machines have tight rectangular shapes, but also stand out because of their transparent character thanks to the large acrylic windows and the use of LED lighting. The condition of the machine can be seen from a distance by the colour of the light. Anton Bax and the designers he worked with were inspired by modern mobile phones. As with the telephone, the grinder is completely black when it is switched off and lights up when it is switched on. In operating mode, the appearance is blue and in service mode, the lighting turns bright white, which ensures good visibility when working. If the machine is in malfunction, it turns red. This makes the new machines not only an attractive appearance in the workplace, but also very functional. The doors are made electrically without visible hinges or screws. And there are also several improvements compared to the previous models. The brush units have been adjusted to make them easier to adjust and the grinding unit has been made more stable. The small machine for the small parts now has standard thickness measurement. If you are working on both steel and stainless steel on one machine and need to change the brushes for this purpose, you can easily place these brushes in the brush storage in the machine, so that they are always at hand.

Q-Fin has also chosen for the striking new design because of the plans to build an international reputation. "Design in mechanical engineering is becoming increasingly important because every DGA wants a decent factory with beautiful machines", says Anton Bax. "In addition, you can distinguish yourself with it." And that was particularly evident at the Blechexpo. Q-Fin showed the F200 XL (for deburring, grinding and/or rounding workpieces from 10 mm to 200 mm wide), the manually operated, mobile TopGrinder and the deburring machine for the finishing of sheet metal parts up to 1200 mm. The grinding specialist from Brabant emphasized that with the small machines for small products and the wide machines for large products, all common products can be finished. Faster and better than with any other machine. "We control the finish of each cutting product and are convinced that our machines are superior. With a complete set of one large and one small machine (so-called Ultimate set), you can solve your entire deburring issue." With this message, Q-Fin scores particularly well with experienced users. "Because they recognize the problems and know what the difficulty is when deburring - especially of small parts. They see that our machines offer a perfect solution for this."

Benier invests in Q-Fin deburring machine

Over 100 years, Benier designs and builds systems to produce and process all kinds of dough. These systems are used in both craft bakeries as well as the industrial bread production lines.

Benier is paying a lot of attention to the quality of the dough and the careful management of the process, for example with measuring the dough. Besides they are using modern mechanical techniques and advanced control technology for a craft processing method.

Benier has a lot of experience with a large amount of products consisting of dough, whether the products are bread, buns, baguettes, panettone or pizzas. They offer a wide range of production processes, from traditional standard processes to custom-made processes.

Joost Wevers, manager productions at Benier Nederland:“We do everything by ourselves during the process of developing and building the machines. For example, we are engineering, producing, laser cutting, assembling and testing of the mechanicals and software of the machines before they go to the customers.”

Manual deburring is time-consuming
The hygienic design is of great importance to our customers. The cleanability of the machines shows the translation of this hygienic design. The machines of Benier are easy to clean because of the round edges and the lack of burrs. Besides by deburring and edge rounding the sheet metal parts of the machines, the customer can use the machine safely. Up to a year ago, Benier did this deburring and edge rounding process manually. According to Joost Wevers, this process was time-consuming, it was daily a two-man job.

Benier wants to deliver a consistent quality
Benier has done this process manually for a long time. But with a constant tightening of the customer needs, the company has looked for another solution. It was clear they needed to invest in a deburring machine. According to Benier, the greatest benefits of a deburring machine are the consistent quality of de edge rounding, a professional look of the sheet parts and the surface has no scratches or strange structures.

The combination of multiple machines gives us the speed we were looking for
Why Benier has chosen for the machines of Q-Fin? According to them, because Q-Fin is able to offer a combination of machines for small and large sheet metal parts. When the company looked to their production of the sheet parts, they saw that 80% of the products were smaller than 200 mm. The other 20% was larger than 200 mm. When you purchase one machine for all of the sheet metal parts, the small metal parts will unnecessarily make long strokes. This wastes time and is inefficient. But Q-Fin has an optimal combination, which suits perfectly with the processes of Benier. The F200 is capable of processing the small metal sheet parts while the F1200 suits the larger metal parts.With these machines, Benier is able to do deburr more materials than with every other machine. Furthermore, Q-Fin has no nonsense equipment and that is what Bernier was looking for. The machine is easy to control and has no endless settings on big screens. Everyone is able to work with the machines when they had a basic explanation. The machines are also almost without interferences.

Part of the process
The machines of Q-Fin are integral part of the processes at Benier. The nested sheet metal parts are going straight after the gathering through the deburring machines. So nobody can hurt himself. The process is optimised and the support of Q-Fin is fine. During a recent removal, Bernier had a small issue with the machines. One call to Q-Fin made this problem solved.

The total chain is only as strong as its weakest link

This statement obviously applies to everything. All coating systems can be tested among the most spectacular conditions and with the highest marks in the tests, but always mention reasons why a coating system does not meet.

For each application, it is proposed a particular coating system. For example, it is natural that there is a coating system which is placed in an outdoor installation, on the coast, can now be brought to different demands than to a coating system which is used in a dry environment within and / or applied.

One-, two- or multi-layer systems are therefore always applicable. The obtained layer thickness and the applied coating are therefore always the protective factors of the underlying metal. With powder coating, it is no problem at all to inject 80 microns. For example, one operation on a flat surface. On these surfaces than normally occurs no corrosion.

The biggest problems always rise from the sharp edges and corners. When these sharp edges and corners are not rounded enough or deburred, this will always be the weakest link of the entire coating system.

On an edge or corner, which feels like a razor, is now one gets once insufficient film thickness, and thus this is insufficient protection. Especially in the current architecture, which is widespread perforated panels, these panels will have to meet certain conditions. All edges and corners should be rounded with a radius of at least 0.5 mm. The perforation holes should be as large as possible, most preferably not smaller than 10 mm. When the starting material meets these requirements, it will always have a two-layer coating system in order to achieve sufficient edge coverage and therefore protection. "Corrosion consciously construct" may not be sufficient attention. Though it is just to strengthen the weakest link.

Q-fin provides rounding and remove oxide skin

Q-Fin is a company that has perfect finishing and deburring machines. This Dutch manufacturer develops and builds machines for deburring, grinding and finishing of metal parts. The machines can also remove an oxide layer in one pass. Recently, Q-fin delivered the hundredth machine. In just three years! The first deburring machine     Q-fin brought to market was the Fierde 200 with two stations for finishing small parts up to was 200. Followed closely by Fierde 200 XL, a three-station machine, which can deburr up to 200 millimetres wide. This machine can achieve a higher rate in the side break.

In the meantime Q-Fin is working hard to develop the Fierde 1200, for deburring large wide metal parts. This machine has four crossed and counter-rotating brushes, which oscillate back over the working width. The result is an optimal finish and a non-directional finish to the surface. In addition, there is an option for a vacuum or magnet belt so the machine is suitable for stainless steel, aluminium, steel and various plastics. Last year Q-Fin introduced the TopGrinder, a semi-automatic deburring machine, which you can find throughout Europe. And Q-Fin has a newest addition in their product range. In April the first test will be the introduction of the ‘Edge Rounder 1200’


This machine provides a guaranteed finish of R = 2 mm or larger on all edges. It draws the power of Q-fin: the customer has a problem and Q-fin finds a solution! www.q-fin.nl, the fastest solution of deburring, round edging and finishing.
