The working principle of wire spark machine
Wire cut electrical Discharge Machining (WEDM), sometimes called wire cutting.
The basic working principle is the use of continuous movement of fine wire (known as the electrode wire) for the electrode, the workpiece pulse spark discharge erosion of metal, cutting molding.
It is mainly used for processing all kinds of complex shapes and precision of small parts, such as punching die punch, die, convex and concave mold, fixed plate, discharge plate, forming tool, model, EDM metal electrode
, A variety of fine holes, slits, any curve, with the processing margin is small, high precision machining, short production cycle, low manufacturing cost advantages, has been widely used in production, the current domestic and international spark
WEDM has accounted for more than 60% of the total number of machine tools.
