The main features of EDM 电火花加工主要特点

1 can be processed ordinary cutting methods difficult to cut the material and complex shape of the workpiece;
2 no cutting force when processing;
3No defects such as burrs and knife marks grooves;
4 The tool electrode material does not need to be harder than the workpiece material;
5 Direct use of electrical energy processing to facilitate automation;
6 after the processing of the surface of the degenerative layer, in some applications must be further removed;
7 Purification of working fluids and handling of smoke pollution during processing are cumbersome.

The main uses of EDM are:
1 machining of molds and parts with complex shapes of holes and cavities;
2 processing of various hard and brittle materials such as hard alloys and hardened steels;
3 processing of deep holes, shaped holes, Deep grooves, narrow slits, and cutting sheets;
4 Tools and gauges for forming tools, templates, and thread rings.
