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

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.


Q-Fin Super Edge Rounder SER600
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!

The 600mm wide machine (F600-MAG) for steel laser cut products!

The 200mm wide machine (F200 XL-VAC) for stainless steel and aluminium laser-cut products.

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.
