A deburring machine can do more! Arku Maschinenbau will show what is possible at the Blechexpo 2023 trade fair: At booth 1001 in hall 1, trade visitors can see what automation can do for deburring.

As machines get faster and faster, parts handling becomes a challenge. If, in addition, there is a lack of skilled workers, even smaller sheet metal workers can no longer do without the acquisition of a robot. However, these robots cannot perform all tasks: Until now, for example, they have had difficulties handling parts of very different shapes and sizes. Arku already has a vision robot for loading and unloading straightening and deburring machines for larger sheet metal parts.

At Blechexpo 2023, Arku Maschinenbau GmbH, Baden-Baden, Germany, is now presenting an addition to its handling portfolio: a processing cell with the latest EdgeBreaker 6000 deburring machine at its center. It is supplemented by a robot that independently takes over the loading of the deburring machine. This vision robot detects and positions smaller sheet metal parts; thanks to a cooperation with J. Schmalz GmbH.

Perfectly rounded sheet edges

The EdgeBreaker 6000 performs deburring, edge rounding and surface finishing of the parts. With its rotating brushes, the deburring machine achieves a more uniform rounding than any other process, up to 2 millimeters radius if required. In addition, Arku has designed it so flexibly that it can be used for completely different parts, shapes and dimensions. This makes the EdgeBreaker 6000 ideal for laser job stores.

The presentation of the deburring machine complements Arku with deburring tools and services. Interested parties can thus find out at the booth about the correct interaction of machines and tools to achieve optimum results in their sheet metal processing. Visitors will also find the right contacts on site for information on the subject of contract straightening or contract deburring.
Another highlight at the booth is the topic of coil laser systems, which Arku has developed in cooperation with Trumpf. This allows sheet metal workers to work from coil even with medium batch sizes.

Material losses due to fixed blank sizes are thus a thing of the past: A coil laser system can be used to cut exactly the right amount of sheet metal needed for a specific component. The nesting of sheet metal parts becomes much easier without the format limits. In this way, material can easily be saved, and even up to 30 percent is possible for large-area parts. This means that sheet metal workers only have to carry a small amount of waste to the scrap box – and that saves money.

Coil laser systems offer numerous advantages

In addition, laser cutting systems fed with strip material offer significantly higher machine runtimes than systems that process sheet metal. Another additional advantage is the lower tooling costs. Last but not least, these coil laser systems run completely automatically – there is no need to keep extra operating personnel on hand.

Straightening units are also integrated directly into the coil laser systems. They eliminate not only coil curvature but also residual stresses in the sheets. In this way, sheet metal cutouts can be prevented from shooting up during laser cutting and damaging the laser head. The sheet surfaces also become smooth and even. Users benefit from increased process reliability with the straightened sheets.

Low stress and flat parts thanks to straightener

Arku also demonstrates the importance of straightening sheet metal parts after cutting to remove unevenness and residual stresses. On live display at its booth is a FlatMaster 55 leveler, which incorporates all of Arku’s expertise from nearly 60 years of leveler manufacturing and more than 25 years of contract leveling. The Arku part levellers can bring sheets with a thickness of up to 60 millimeters into a flat condition with the lowest possible residual stresses.

Short profile Arku

Founded in 1928, the family-owned company Arku Maschinenbau GmbH is the market leader in straightening technology with almost 60 years of experience. Arku offers 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 (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 over 200 people worldwide.
