Abstract
PURPOSE:To highten the crest value to improve the machining speed by providing the condenser and the discharge control switch near the machining clearance to which the pulse power source is connected. CONSTITUTION:The machining pulse which becomes the series of the machining pulse is generated from the machining pulse power source by the on-off switching control of the switch 4. The condenser 7 which is charged by the feeding machining pulse through the rectifier 10 is connected with the machining clearance. The condenser 7 discharges into the machining clearance through the switch 8 which is continued by being turned on. The discharged current discharges the pulse of which crest value is increased as the condenser 7 is provided near the machining clearance.
