Levelers, Deburring Machines, & Coil Lines

Perfect surfaces: Thanks to the levelers, deburring machines, & coil lines from ARKU – metal panels and parts with burrs, unevenness or internal stresses are now an issue of the past. For your competitive advantage.

ARKU – Metal Leveling & deburring from a single source.

Innovation and precision. With 90 years of experience in sheet metal processing, we are one of the leading experts for sheet metal processing machines.

As the technology and market leader in leveling technology, we offer the world’s broadest spectrum of high-performance precision roller levelers. These range from levelers for thin or complex parts to straighteners for thick plates and even AHSS materials. All of these systems ensure perfectly flat, stress-relieved sheets and parts.

As an innovation leader, we have expanded our range of expertise to include deburring, edge-rounding and oxide layer removal with our line of deburring machines. Leveling and deburring are perfect compliments for sheet metal processing and ensure outstanding results.

Two fundamental steps in sheet metal processing – now from a single source.

Deburring of plasma and flame-cut parts.

The EdgeBreaker® 4000 high performance deburring & finishing machine is built for processing materials with tough adhering burrs after plasma and flame cutting (oxyfuel). Its trademark is the powerful grinding drum. It is able to reach all the corners by flexing slightly around the material. Cross-running brushes are outfitable with a variety of media for individual processing of edges. Double-sided processing, because time is money!


Double-sided processing in a single pass

The EdgeBreaker® 4000 processes plasma and flame-cut parts on both sides in just a single pass. You are able to save 50% of the time compared to working with a single-sided machine.

High-performance deburring

The oscillating grinding drum is the main tool for removing the tough adhering burrs. With a diameter of 420 mm (16.5″) and thanks to a flexible grinding surface, it is able to reliable remove any burrs from plasma and flame-cut parts. Additionally, the EdgeBreaker® is also capable of compensating for uneven surfaces in the material.

Quick changing of the abrasive media

The EdgeBreaker® 4000 was designed with the goal of keeping downtime to a minimum. All abrasive media of the various processing units can easily be changed, and the inside of the machine is purposefully accessible for faster routine cleanings and maintenance.


The touchscreen HMI is truly intuitive. This feature enables even new operators to quickly and easily setup the machine. It can even give you guidance on operating and maintenance. For efficient processing and minimal operator error.

Automatic calibration / wear compensation

For consistent results, it’s important to know the remaining length of the abrasive media. This is crucial to producing repeatable, high-quality parts. The EdgeBreaker® 4000 measures the remaining length of the abrasive media and automatically compensates for the wear, further minimizing operator error.
