Features
DK77 series Medium speed wire cutting EDM machine features:
1. Molybdenum wire and the workpiece surface must be processed to maintain a certain gap between the width of the gap by the working voltage, processing capacity and other processing conditions may be.
2. Demanding high insulation is to facilitate the generation of pulsed spark discharge, the liquid medium also exclude the gap between the galvanic products and the role of the cooling electrode. Molybdenum wire and the workpiece surface to be processed to maintain a certain gap between, if the gap is too large, the voltage between the electrodes can not break the electrode medium, you can not produce spark discharge; if the gap is too small, it is easy to form a short circuit connection, it can not generate electricity Spark discharge.
3. Must adopt the pulse power, namely the spark discharge must be the pulse, intermittent, ti in Fig. 1 is the pulse width, to is the pulse interval, tp is the pulse period. In the pulse interval, the gap medium ionization, so that the next pulse can be between the two poles breakdown discharge.
