PURPOSE:To standerize the machining condition and to increase the machining speed by connecting the auxiliary current to feed the discharge current of the condenser with the machining clearance other than the main machining power source which generates machining pulse series. CONSTITUTION:The machining pulse is fed to the machining clearance to discharge-process by the on-off switching control of the switch 4 from the main machining power source. The discharge current of the on-off control of the switch 10 from the auxiliary power source is combined with the machining pulse series. The discharge current of the condenser 9 is charged by the high voltage series power source 8 from the main mach-ining power source seriese power source 3 and impulsively discharged by the onconducting of the switch 10 to become the high current pulse. |
