The EDM machine is doing?
You said EDM machine called the EDM machine! EDM is immersed in the working fluid between the poles of the electric pulse discharge erosion corrosion in addition to a special processing method of the conductive material, also known as electrical discharge machining or electrical erosion processing, the English referred to the EDM. EDM is mainly used for processing the complex shape of the hole and the cavity mold and parts; processing a variety of hard, brittle materials such as cemented carbide and hardened steeldrill edm, etc.; processing deep pore Hole, deep grooves, slit and cut thin slices; forming and processing of various tools and measuring tools, templates and thread ring gages.
EDM processing the ordinary cutting is difficult to cut materials and complex shapes; no cutting force when the processing; does not produce defects such as burrs and marks grooves; tool electrode material need not be harder than the workpiece material; direct use of electrical energy processing, easy to automation; processed surface of the metamorphic layer, in some applications need to be further removed; working fluid purification and processing of smoke pollution treatment is too much trouble.
