Application of wire cut EDM machining
Wire cut EDM machining is mainly used to process various punch tie, plastic mold, Powder metallurgy mold and etc, which have 2D and 3D faces combined, or components. It can also cut various sample plate, magnetic steel, Silicon Steel Sheet, semi-conductive material or precious metal. Furthermore, it is able to do tiny machining, abnormal shape groove or machining of standard defect of sample parts, widely used in electrics, precious machine tools, light industry, army industry and so on.
- Mold machining
Wire cut 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,
To mechanical parts machining, wire cut EDM is suitable to machine parts with large varieties and small quantity, special material which is not easy to processed by conventional machines, special gear, forming cutting tools, various shape holes, please check figure 1-2.
When try to make new product, use wire cut EDM machine to cut parts out of workpiece, there is no need to make molds, producing time is shortened obviously, at the same time, cost is reduced. Besides, as it is easy to adjust electrical parameters of wire cut EDM, so it is possible to overlap thin plate and cut together to increase machining efficiency.
And wire cut EDM machine can also machine parts with tiny gap, narrow slit and complex shape.
