Abstract
The method of sparking machining to shape or finish a metal workpiece, applying said piece against the surface of a rotating wheel while a circuit that provides a series of short spark discharges, initiated by overvoltage and spaced in time, is connected between the wheel and the piece characterized by the fact that between the latter an explosive discharge or spark gap is maintained providing the wheel with a porous surface and covering said surface of the wheel with a semisolid dielectric of grease or wax.
