Electro-chemical machining (ECM) is a fascinating production method, because the technology involves virtually no workpiece contact: A direct current, or pulse, is used to polarize the workpiece positively, to create an anode, and the tool negatively, for the cathode. An electrolyte solution flows between the two, and metal ions detach from the workpiece. The components are not exposed to any mechanical or thermal stress during the process.

Increasing cost pressure, high demands on part quality and frequent change of batches – the manufacturing of car brake discs is a difficult field. Particularly in the spare parts market, where users must request individual machining solutions that can be retooled for new workpieces without long downtimes.
