Process and device for mechanical grinding or sharpening of workpieces by use of electrically conductive grinding or sharpening tools

摘要: A process for the mechanical sharpening of workpieces using electrically conductive tools provides that, procedurally, first an electric spark gap is created between a tool (18) and workpiece during contact on (10), position determined by arc discharge. Subsequently, process, or potential disconnected adjusted to such value that essentially only material removal occurs. The especially advantageous as executed device which electro-erosion processing effects electro-erosion, because then control circuit (32) present these purposes can be used not treatment, but also tool.
