The first prerequisite for the discharge machining of the die:
1 must make the click and the workpiece is machined surface to maintain a certain discharge gap, the gap with the processing conditions, usually a few wires to dozens of wire. So if the gap is too large, the voltage between the two electrodes can not breakdown of the medium, and thus can not generate electricity, if the gap is too small, it is easy to line into a short circuit, the same can not produce electric spark discharge. Therefore, in the process of electric spark machining, it is necessary to have the automatic feed and adjustment device of the electrode.
2 spark discharge must be made in an instant. After the discharge of a period of time, the need to rest for a period of time, so that the heat generated by the discharge can not be transmitted to other parts, the discharge was limited to a very small range. Otherwise, like a continuous arc discharge, so that the surface burn and can not be processed, so the electric spark machining must use the pulse power.
3 spark discharge must be carried out in a liquid medium with a certain insulation performance.
