ECM – More than just deburring

Electrochemical machining (ECM) is an erosive machining process, using the effect of electrolysis. For this purpose, a tool is placed opposite to the metallic work piece. By applying a voltage between tool (cathode) and work piece (anode), material is eroded from the work piece. The presence of an electrolytic solution in the gap between tool and work piece is of particular importance in this respect.

Benefits of process:

  • non-contact machining
  • no process-related wear of cathode (tool)
  • no structural modifications due to machining at room temperature
  • no unwanted surface erosion
  • no impact of mechanical material properties (hardness, strength) on machinability
  • high degree of reproducibility
  • simultaneous machining of several work pieces

Use of process:

  • Machining of almost all electrically conductive materials
  • Precision-machining, in particular, of gear, engine, hydraulic, and pneumatic components
  • Machining of hard-to-reach spots
  • Machining of thin-walled, filigree, and complex components
  • Generation / introduction of complicated shapes even in the interior of components
