ABSTRACT:
In a method of grinding a workpiece employing a metallic grinding wheel sorting a non-conductive abrasive medium, a cathode is provided in spaced relationship with the abrasive surface so as to define a gap therewith. Electrolyte is caused to flow through the gap, and a low direct current is passed between the grinding wheel and the cathode through the electrolyte so that a small amount of metal is continually removed from the grinding wheel so that material trapped in the abrasive surface is dislodged and flushed away by the electrolyte flowing through the gap.
