1: Two kinds of side repair programs are designed for NC EDM machine. The square side repair scheme with flat bottom is adopted for the rectangle with sharp edges and corners, and the round side repair scheme with flat bottom is adopted for the ellipse with circular or multi curved surfaces. In the process of side repair, the electrode moves and feeds towards the workpiece at an angle. At this time, the tool electrode is controlled automatically by NC from the middle to the outside and from top to bottom, that is, three-axis linkage. This movement mode is not easy to deposit carbon, chip removal and exhaust, will not cause arcing, and has high production efficiency,

2: NC EDM machine X-axis lateral machining split die, high die closing accuracy, productivity can be much higher than z-axis downward machining.

3: A special control is added to the control circuit of the NC EDM machine. When an arc or false short circuit occurs, the pulse power supply is immediately cut off and the energy supply to the cavity is stopped. The electrode temperature will not continue to rise, reducing the possibility of fire.

4: NC EDM machine adopts a complete low-voltage pulse mode after high-voltage breakdown, with equal pulse width. Practice has proved that this pulse mode further reduces the loss of tool electrode, the machined surface is rough and uniform, and the end face loss of tool electrode is very small.

5: The NC EDM machine can use one electrode for rough and finish machining, which saves the manufacturing time and cost of double electrodes, saves the trouble caused by the correction of finish machining electrodes, and shortens the time of mold manufacturing.

6: Self suitable function. The so-called self suitable knife lifting means that the knife will not be lifted when the discharge is stable when the removal of etched matter in the cavity is greater than the generation. When the removal of etched matter in the cavity is greater than the discharge, the balance is broken. At this time, the spark machine will automatically lift the knife and discharge the excess etched matter by using the suction effect of working fluid. When the balance is reached or the discharge is greater than the generation, the knife lifting will be stopped to improve the efficiency.
