In addition, the grinding wheel has a longer life — as much as 50 times longer — and there is less frequent need for truing and dressing than with traditional abrasive grinding methods. The electrochemical grinding process bears some resemblance to creep-feed grinding, in that both feed material more slowly than conventional surface grinding.

Electrochemical machining is the reverse of electroplating. An electrolyte works as a current carrier, and the high rate of electrolyte flow in the tool-workpiece gap washes metal ions from the workpiece (anode) before they have a chance to plate onto the tool (cathode). Modification of this process are used for turning, facing, slotting ...
