method of dimensional machining by electric arc of flat end SUFACES of annular components

摘要

A method of dimensional machining by electric arc of flat end surfaces of annular components, at which working fluid is forced into the end inter-electrode clearance under process pressure. Two components are worked simultaneously, they are rotated non-coaxially in opposite directions, and the arc is excited in the end inter-electrode clearance, which is formed by their end surfaces, moreover the polarity of working periodically changes.
