ABSTRACT:
The electrolytic/electric discharge machining of a workpiece of a non-conductive hard material, for example, ceramic material is carried out by preparing a grinding wheel having conductive regions and non-conductive abrasive regions circumferentially alternately arranged on the circumferential edge of the wheel, and bringing the rotating grinding wheel in contact with the workpiece while applying AC or DC voltage across the grinding wheel and the non-conductive workpiece.
