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 XXL, 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.

Radius 2 in one pass

30-01-2019
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

30-10-2018
 

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).

 

Benier invests in Q-Fin deburring machine

13-09-2017
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.
