Electro-chemical metalworking (ECM)

Electro-chemical metalworking (ECM) is a precise process for shaping and surface finishing metals. The workpiece is immersed in a conductive electrolyte as the anode, while a tool serves as the cathode. By applying an electrical voltage, metal ions are transferred from the workpiece into the electrolyte, causing material to be removed.

The material is removed without mechanical impact, which makes the process particularly gentle on sensitive materials. ECM enables the machining of complex geometries and the finest details with high precision and surface quality. It is used in industries such as aerospace, the automotive industry and medical technology, where high demands are placed on dimensional accuracy and surface quality.

Another advantage of ECM technology is the machining of hard or difficult-to-cut materials that would be difficult or impossible to machine using traditional mechanical methods. This opens up new possibilities in the manufacture and optimization of components that have to withstand extreme loads.
