Top-notch quality can only be achieved with a deburring machine.

Deburring with the EdgeBreaker® 4000. A success story from the Salzgitter Mannesmann Stahlhandel GmbH, Germany.

Large and heavy sheet metal parts, such as those used to manufacture tractors or cranes, are an integral part of the Salzgitter Mannesmann Stahlhandel GmbH (SMSD) portfolio. This includes maximum precision also for workpieces that are produced from thick metal via thermal cutting. At the Zeithain site (Saxony), SMSD manufactures these blanks, including necessary post-processing of various kinds. Most of the materials are up to 40 millimeters thick with dimensions of up to 300 by 500 millimeters.

 

„ARKU had us fully prepared for the expansion of our machine capabilities.“

- Daniel Götze, Product Manager Pre-fabrication at Salzgitter Mannesmann Stahlhandel in Zeithain

 

Deburring prior to leveling is a must

Nowadays, deburred sheet metal parts are a standard when it comes to customer requirements. But at SMSD there was more: In an important framework agreement, the steel trader had promised the customer specific flatness. For that, the metal parts require leveling. However, cutting thick metal requires a lot of energy. It also means that during the cutting process, large burrs are formed. These protrusions, if they remain on the workpiece, can damage the leveling rollers of the leveling machines. Deburring the metal parts before leveling becomes thus indispensable. Beforehand, SMSD were still manually deburring flame cut parts with angle grinders.  

 

Consultation and tests are part of ARKU

Before we purchased from ARKU, we received a comprehensive consultation including a comprehensive test of our production materials in the Baden-Baden Leveling and Deburring Center. Finally, the decision was made: “The EdgeBreaker® 4000 met our expectations. With this system, we are able to process different metal sheets reliably and with consistently high quality,” says Götze.

These thick metal sheets are no problem for the ARKU system at all. The EdgeBreaker® 4000 reliably deburrs and rounds precisely such workpieces thanks to the oscillating grinding drum – on both sides in just a single pass. The machine also masters stubborn burrs and slag, in particular those that are created by thermal and plasma cutters.
