EDM wire cutting can be normal operation, must meet the following conditions:
1, molybdenum wire and the workpiece must be maintained between the surface of a certain gap, the width of the gap by the working voltage, processing capacity and other processing conditions may be.
2, EDM WEDM machine processing, must have a certain insulating properties of the liquid medium, such as kerosene, saponification oil, deionized water, etc., require high insulation is to help produce pulsed spark discharge, liquid media
Also remove the gap between the corrosion products and the role of cooling electrodes.
Molybdenum wire and the workpiece to be processed between the surface to maintain a certain gap, if the gap is too large, the voltage can not breakdown between the inter-polar medium, can not produce spark discharge; if the gap is too small, it is easy to form short-circuit connection,
