EDM is the principle of removing the material on the surface of the workpiece by de-layering the high temperature generated by the spark between the electrode and the workpiece. EDM is suitable for the processing of high hardness conductive workpieces. CNC EDM machines are the best example of EDM.
EDM machining is mainly used for processing various shapes and delicate and delicate workpieces, such as punches, dies, embossing dies, fixing plates, unloading plates, etc. for forming dies, forming knives, stencils, metal electrodes for EDM processing Various micro-holes, narrow slits, arbitrary curves, etc., have outstanding advantages such as small machining allowance, high machining precision, short production cycle and low manufacturing cost. They have been widely used in production, and the current domestic and international electric sparks Wire cutting machines account for more than 60% of the total number of electric machine tools.

1. EDM processing speed and surface quality
Molds in EDM processing generally use coarse, medium and fine grade processing. Roughing is realized by high power and low loss, while the relative loss of medium and precision machining electrodes is large, but in general, the middle and finishing allowances are small, so the electrode loss is also very small, which can be compensated by machining size control, or Ignore it without affecting the accuracy requirements.
2. EDM carbon residue and slagging
EDM processing can be carried out smoothly under the conditions of carbon residue generation and carbon residue removal. In practice, carbon slag is often sacrificed at the expense of processing speed, such as high voltage, large pause pulse wave, etc. in middle and finishing. Another reason for the exclusion of carbon residue is that the shape of the machined surface is complicated and the path of the chip removal is not smooth. Only actively create conditions for good exclusion, and take some measures to deal with it.
3. EDM workpiece and electrode loss each other
EDM discharge pulse time is long, which is beneficial to reduce electrode loss. EDM roughing generally uses long discharge pulse wave and large current discharge, and the processing speed is small and the electrode loss is small. In the case of finishing, the small current discharge must reduce the discharge pulse time, which not only increases the electrode loss, but also greatly reduces the processing speed.
