Abstract

PURPOSE:To improve the shape and the dimensional accuracy through simultaneous radius chamfering at the open rim of small diameter hole drilled on the work by electrolysis. CONSTITUTION:A small diameter hole 11 is drilled on a work 12. A tool electrode 13 larger in diameter than the hole 11 is arranged as opposed to the opening 11A. The work is connected to the anode and the tool electrode 13 to the cathode. With an electrolyte interposed, a formation current (an anode film formation current and an electrolytic working current for eleuting the anode are alternately energized. While an external surface 12A following the open rim 11 is protected with an anode film 15, a radius chamfering is gradually made on the hole rim. The size of the radius surface is determined by the frequency of the nergization.
