  • What is Electrochemical Machining?

    Paul Scott Last Modified Date: August 26 2020 . Electrochemical machining (ECM) is a metal machining process involving the removal of material from a workpiece by means of electrochemical erosion. This process is achieved by passing a high current electrical charge from the positively charged workpiece through an electrolyte solution to the negatively charged "cutting tool."
