PURPOSE:To remove working chips without vibrating the top edge of an electrode member by working an electrode shaping electrode in revolution and removing the working chips at the position depared from the electrode member. CONSTITUTION:Pulse voltages are applied into between an electrode member 1 and an electrode shaping electrode 10 from a pulse generator 3, and the electrode shaping electrode 10 installed onto a table is revolved, intermittently generating arc electric discharge, and the electrode member 1 is finished to the electrode having a desired diameter by applying a prescribed cutting-in in the direction of X-axis in this state, and then applying working-feed in the direction of Y-axis. During this time, the working liquid 11b supplied from a high-pressure pump 11a is jetted out onto the outer peripheral part of the electrode shaping electrode 10 from a nozzle 11c installed at the position departed from the electrode member 1, and the working chips adhering onto the above-described part can be removed. |
