Description

technical field [0001] The present invention relates to an electric discharge machining device for electric discharge machining and a lifting action control method. Background technique [0002] In an electric discharge machining device for engraving electric discharge machining, if the number of discharge pulses per unit time deviates from the optimum range, that is, the so-called optimum value, the machining speed will decrease and efficient electric discharge machining will not be performed. In order for the electrical discharge machining device to efficiently perform electrical discharge machining, it is necessary to secure an optimum value for the number of electrical discharge pulses. The number of discharge pulses is affected by the concentration of machining chips deposited in the machining gap between the electrode filled with machining fluid and the workpiece. In the electrical discharge machining device, when the concentration of machining chips is too high, it i...
