Electrochemical Machining – a fascinating technology of net-shape fabrication

Electrochemical Machining (ECM) is a non-conventional technology to shape metals. The technology based on the controlled anodic dissolution of metals. Thereby, the shape of the work tool (or cathode) is reversed reproduced on the work piece. The process works at very high current densities of a few hundred amps per square centimeters. Now other electrochemical technology works at such high currents which are up to 1000 times higher in comparison with e.g. electroplating. Regarding the fact that work tool and work piece are separated by the electrolyte gap no impact of mechanical stress is created into the work piece and otherwise the work tool is not abrasive loaded. Additionally, due to the fact that the removal rate of the material is independent of the hardness of the material the technology is specific suitable to machine high strength or very brittle materials. Further advantages are listed below:

  • No relevant thermal impact into the workpiece
  • No burr formation
  • Great versatility on geometrical requirements
  • High surface quality

Unfortunately, ECM is still less popular in comparison with comparable non-conventional technologies like electrical discharge machining (EDM). This website should offer a platform for the ECM community to exchange knowledge, current challenges and experiences. Experts from industry and academia are invited to use this platform for discussion and networking to overcome new challenges of the ECM technology.
