In deburring, the machine is only one part of the system. Just as important are the deburring tools to achieve the desired quality at the sheet edge. Arku showed at Blechexpo 2021 in Hall 1, Booth 1001, how to process sheet metal parts faster with the right tools and thus save costs.
The machining result on sheet metal edges is often a compromise between part throughput and material removal. If, for example, the speed at which the parts pass through the machine is increased during rounding, the edge radius is reduced. If, on the other hand, the radius at the edge is to be increased, the machining speed must be reduced. In other words, sometimes more and sometimes fewer parts run through the machine in the same time.
By using new tools, Arku has succeeded in doubling the machining speed while maintaining the same rounding result. This leads to process cost savings of up to 30 percent.
The choice of the best deburring process is the result of machine and tool. The latter can be sanding blocks, roller brushes, disc brushes or sanding belts.
Even deburring tools of the same type can produce different results. They differ, for example, in the trimming or the abrasive grains. The right choice of tools can improve the results for different applications. However, as the suitability of the tools for different material types, sheet thicknesses or contours varies, Arku has a selection of different tools up its sleeve.
The interaction between tool and machine has also been further coordinated at Arku. Whereas previously tool selection, setting values or grinding speeds had to be adjusted to the best of one’s knowledge, this is now done by the Arku Wizard: intelligent software in the machine that links workpiece, tool and machine data.
Enter basic data and you’re done; the machine does the rest
The machine control in the EdgeBreaker 6000 requires the operator to enter the nature of the component and the desired machining result. These are, for example, sheet thickness, material or thickness of the burr, as well as the required edge rounding or the surface finish after the pass.
The machine combines the inputs with the data from the tool and machine and adjusts itself automatically, achieving the result at the best possible machining speed. This is unique in the market and a great customer benefit. This is because the machine operator no longer has to try things out, incorrect settings are avoided and empirical values are subsequently stored in the machine.
To ensure that this also works with increasing wear of the tools, the EdgeBreaker 6000 has an automatic wear measurement. This is automatically taken into account and compensated by the control system, so that the operator is spared re-measurement and conversion.
Arku short profile
Founded in 1928, the family-owned company Arku Maschinenbau GmbH is the market leader in straightening technology with more than 50 years of experience. Arku claims to offer the world’s largest selection of high performance and precision levelers, as well as deburring and rounding machines. In addition, Arku has its own business unit for parts handling around the straightening and deburring machines.
With its headquarters in Baden-Baden, Germany, and ISO-certified subsidiaries in Kunshan (China) and Cincinnati (Ohio/USA), the company covers markets in over 30 countries. The product range includes precision straightening and deburring machines for parts, automated parts handling with robots and complete coil lines. The Arku machines are used in industrial sheet metal processing. This is particularly the case in the automotive industry, mechanical engineering and shipbuilding. Arku Maschinenbau employs approximately 200 people worldwide.
