Abstract
PURPOSE:To provide a stable electric spark machining condition and prevnet from a sustained arc electric discharge by detecting the average voltage across the electrodes and the sustained arc discharge voltage, allowing the detecting differential voltage to control the machining electrode clearance and the power pulse of machining power source. CONSTITUTION:An electric spark machine operates by applying an electric discharge voltage pulse applied from the power source 1 to an electrode 2 and a workpiece 3, permitting to enter the average voltage of across-electrode voltage pulse which is detected with an across-electrode voltage detector 4 into a differential amplifier 5, wherewith the voltage applied with a standard voltage set unit 6 being compared, by these differential voltage a servo motor 7 being controlled to operate automatically to feed the electrode 2. In this case the sustained arc electric discharge pulse detector 11 is connected in parallel with said voltage detector 4, allowing to enter respective output voltage into the differential amplifier 12, causing to operate similarly a servo motor 7 by the differential voltage applied, and controlling a machining current and the like by means of a comparison amplifier 8.
