EDM usage instructions 电火花加工使用说明

EDM can process difficult-to-cut materials and complex-shaped workpieces by ordinary cutting methods; there is no cutting force during machining; no burrs, knife-mark groove, etc.; tool electrode materials are not harder than workpiece materials; Automated; after processing, the surface has a degenerating layer that must be removed in some applications; the purification of the working fluid and the smog pollution generated during the processing are troublesome.

EDM is mainly used to process molds and parts with complex shapes of holes and cavities; to process various hard and brittle materials such as hard alloys and hardened steels; to process deep holes, shaped holes, deep grooves, etc. Slits, cutting sheets, and other tools and gauges for forming tools, templates, and thread rings.
