The EDM machine is doing?

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 steel, etc.; processing deep pore Hole, deep grooves, slit and cut thin slices; drill edmforming 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; 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.
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.
