ABSTRACT:
An electric discharge surface conditioning apparatus includes a discharge electrode consisting of an assembly of alternating conductive and non-conductive discs which rotate about an axis. The surface of the conductive discs includes a specific pattern of slots to effect a pumping action thereby enhancing the electric discharge efficiency by circulating the fluid away from the surface of the workpiece being machined. A control arrangement for controlling the orientation of the described electrode is provided.
