Electrochemical Machining (ECM) Micro Surfaces GmbH

Electrochemical metal processing is based on the principle of electrolysis.. The tool is connected as a cathode, and the workpiece as an anode to a DC voltage source. The workpiece processes the charge exchange, which takes place in an aqueous electrolytic solution between cathode and anode.Contours, annular channels, grooves, or inner forming are thus generated with no contact, and with the
