Electrochemical machining (ECM)


Electrochemical Machining (ECM) is a non–contact processing method.

The mechanism of dissolution (removal of metal) during electrochemical machining is based on the
process of electrolysis. Metal removal occurs in accordance with Faraday's law. It means that amount of
metal removed is proportional to electric current intensity and process time.

Advantages

  • high machining performance (linear metal removal rate in precision processing modes is 0.3 mm/min.)
  • the absence of the electrode tool wear permits to provide for a high machining accuracy and repeatability and also reduces operating costs for mass product manufacturing
  • finishing processing is not required
  • high quality of the processed surface
  • the absence of the defect layer and burrs on the surface
  • under machining the formation of thermal stresses and microcracks on the surface of the part are excluded
