Power-supply unit and wire electrical discharge machining manner for wire electrical discharge machining

摘要

The impulse power source which is the alternating current high frequency voltage intermittent supply means which impresses the alternating current high frequency voltage to between the alternating current high frequency oscillation amplifier (4) and the aforementioned pole and stop it had (5) the wire electrode (1a) and in the power-supply unit for wire electrical discharge machining which uses the alternating current high frequency power source where the workpiece (2) impresses alternating current high frequency voltage between the poles. At the time of wire electrical discharge machining by the power-supply unit for this wire electrical discharge machining, the wire electrode (1a) and as it can suppress the vibration of the wire electrode (1a) the workpiece (2) with electrostatic force between, the workpiece (2) to improve it is possible the true direct precision of adding management it is possible to make surface roughness small.
