Explanation: ECM (Electrochemical Machining): The mechanism in the ECM process is like EDM concept-wise. In ECM, a high current is passed between the tool (cathode) and the workpiece (anode), through a conductive fluid (electrolyte), instead of a dielectric in case of EDM. The ECM process makes use of an electrolyte and high …

The ELECTROCHEMICAL GRINDING (ECG) process does not leave the typical shiny finish of abrasive grinding. This is because there is no smearing of the metal as in conventional grinding. A 16 micro inch finish or better can be achieved but it will have a matte (dull) rather than a polished look.
