FOCUS ON SURFACE FINISHING
The combined work of the EdgeBreaker ® and the FlatMaster ®: the parts are deburred, edge-rounded and levelled. The results: flat parts with rounded, burr-free edges.
Efficiency in focus
For several years, two operators at HALLER Metall worked with the ARKU levelling machine— one loading the system and the other unloading and stacking the parts. At the same time, two additional operators were assigned to an older, wet deburring machine.
However, the shortage of skilled workers is being felt everywhere, including at HALLER Metall.
“ Finding qualified personnel is a major challenge, and that’ s unlikely to change,” Heinrich confirmed.
He and his team therefore looked for ways to make processes more efficient— and once again turned to ARKU. The idea: since all sheet metal parts must be deburred before levelling, why not link the FlatMaster ® 88 with an EdgeBreaker ® 4000 deburring machine?
As before, the specialists from HALLER Metall insisted on testing their parts at ARKU’ s facility. They then purchased an EdgeBreaker ® 4000. Unlike the old wet deburring machine, it processes both sides of the part simultaneously.
“ This eliminates at least one additional pass and the need to flip the parts in between,” Nau explained.“ The machine’ s powerful deburring roller removes even stubborn burrs from fibre laser-cut parts. The second unit, equipped with deburring brushes, cleanly rounds the edges.”
Heinrich highlighted another advantage over the old wet deburring machine:“ A dry deburring machine is significantly easier to maintain,” he confirmed. through the combined EdgeBreaker ® and FlatMaster ® line. The double-sided deburring machine requires a minimum part size of 200mm“ but that applies to 80 per cent of our parts,” said Heinrich.
The primary material processed is structural steel, although stainless steel and aluminium are also used.
“ As with any machine, it must be thoroughly cleaned before changing materials,” Heinrich added.
At HALLER Metall, production is therefore organised so that as many aluminium or stainless-steel parts as possible are processed in batches during a material changeover. This allows employees to avoid some of the cleaning cycles for the EdgeBreaker ®. The benefits of the ARKU machines are clear.“ We have achieved better quality. That reduces costs because we spend less time on rework,” Heinrich concluded with a smile. n

Smart linking reduces staffing requirements
At HALLER Metall, the EdgeBreaker ® and the FlatMaster ® are directly linked by conveyor belts. As a result, only two operators are now required: the first loads the parts onto the levelling machine and the second removes the parts at the outlet of the deburring machine and stacks them.
Today, all parts( that are large enough) run
