本文介绍的是使电极和工件之间的间隙即放电间隙保持一定的控制回路。在电火花加工中,不论电源多合适,若放电间隙的状态不一定的话,则无法指望稳定的加工。如前述那样,往电极和工件之间加电压,使电极渐渐接近工件,总会到达发生火花放 This article describes the control circuit that keeps the gap between the electrode and the workpiece, ie, the discharge gap. In EDM, regardless of the power supply more appropriate, if the discharge gap of the state is not certain, you can not expect stable processing. As mentioned above, to the electrode and the workpiece between the voltage, so that the electrode gradually close to the workpiece, will always reach the spark discharge
