EDM is widely used to machine various molds, such as punch die, squeezing die, powder metallurgy mold, bend mold, plastic mold(see figure 1-1). Among these different kind molds, cutting punch die take a great share, to precious punch die machining, wire cut EDM machining is a indispensable technology. By adjusting different compensation value while programming, wire cut EDM can cut terrace die, punch plate, stripper plate and etc, it is easy to meet the requirement of mold fitting clearance and machining accuracy.
Advanced punch dies have characteristics of complicated structure, big producing difficult, high accuracy, long life, high efficiency and low consumption ratio of material. These new advanced technology of mold also bring continuous development of wire cut EDM technology,
