What's ECM
(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.
