Precision levelers for thick metal parts & plates


ARKU offers you an extensive portfolio of roller levelers for flattening and stress-relieving metal plate and thick parts after flame (plasma and oxyfuel) cutting. The machine can also flatten the entire metal plates prior to cutting as well. Different machine models are used depending on the material specifications and flatness requirements. Material type, geometry, quantity and part dimensions all influence the choice of the ideal precision leveler. Always with one goal in mind: to precisely flatten and stress-relieve your flame cut parts.  

Here you will find an overview of our precision levelers.

Interlink and automate precison levelers

The combination of different precision levelers and deburring machins can be used if a single machine cannot achieved the necessary results. Thanks to all of our precision levelers and deburring machines being industry 4.0 ready, they all can be interlinked in a single processing line. This also applies to the integration of planned or existing processing lines. That way, you can get a full turnkey automated leveling and deburring line from ARKU.
