Abstract

PURPOSE:To enhance the processing speed in electric discharge machining by equipping the power supply for wire-cut electric discharge machining with a capacitor in connection to DC power supply and a switching element to control discharging of electric charges on said capacitor or refraining therefrom. CONSTITUTION:This power supply for wire-cut electric discharge machining is equipped with capacitors C1-C3, resistances R1-R5, transistors Q1-Q6, AND gates A1-A3, OR gates OR1-OR3, a comparator COM, ring counters RC1, RC2, an inverter IN and multi-vibrators M1-M5. The voltage comparator COM thereamong is to compare the voltage between a wire electrode WR and a work to be processed W with a voltage VG obtained by dividing by resistance R4, R5 and with a reference voltage VL and give an output of ''1'' while the voltage V is higher. In such a way this arrangement is furnished with a plurality of capacitors connected to a DC power supply through a switching element of transistors Q4-Q6 and a switching element consisting of transistors to control discharging therefrom.
