Deburring machines: keep a clear edge.

Quality-conscious ARKU customers show how our solutions for fully automated deburring are successful during operation.

Straub, Germany: EdgeBreaker® 4000.

Eisen- und Stahlhandel Straub GmbH from Lichtenau, Germany, processes more than 4,000 tons of pre-manufactured parts per month. The company focuses on cutting and bending reinforcing steel as well as cutting, drilling and sandblasting steel profiles. The plant located nearby in Bühl manufactures flame-cut and welded parts up to 200 mm thick using high precision oxyfuel gas and plasma welding.


The growing need for perfectly leveled, deburred and edge-rounded flame-cut parts in small and large series with demanding time and quality requirements.

Solution from ARKU:

The EdgeBreaker® 4000 – for sheet thicknesses from 0,8 to 80 mm.

At Straub, four employees previously tackled the task of removing the millimeter-thick burrs with angle grinders. They needed around three days for 1,000 parts.

Over the course of the year, Straub required up to 20 angle grinders and the corresponding grinding discs to do this job. The deburring equipment cost several thousand euros per year.

Today the EdgeBreaker® 4000 carefully removes undesired burrs using an oscillating drum while transverse rounding units equipped with sanding blocks round the sharp edges on both sides.

Precise, efficient and in a matter of seconds.

"With the EdgeBreaker® 4000 we not only have a better working climate thanks to less noise and dust, but we also process significantly more parts in the same time."

- Simon Straub, Head of Production

  • Straub: EdgeBreaker® 4000.

    Growing demand for precisely leveled, deburred and rounded parts that have been flame cut is what sent Straub on a search for a solution. Especially since parts in small and large quantities, with high time and quality pressure were required.

Benefits for the customer:

  • Significant time and resource savings
  • Higher capacities for new orders
  • Consistently high quality of the parts
  • Improved working atmosphere

Given that the throughput rates will increase considerably, Straub is optimistic about the future. The system enables the company to reinforce its solid market position and strengthen the German production site.
