What is the electric discharge machine?
Slits and cutting sheets, etc .; processing of various forming tools, molds and thread gauges and other tools and measuring tools.
EDM is mainly used for processing molds and parts with holes and cavities of complex shapes; processing of various hard and brittle materials such as hard alloy and hardened steel; processing deep hole, shaped hole, deep groove,
EDM is the use of immersion in the working fluid between the two electrodes between the pulse discharge caused by the erosion of the conductive material of the special processing methods, also known as discharge processing or electro-erosion processing, the English referred to as EDM.
You said the electric discharge machine is called EDM!
EDM can be used to process ordinary cutting methods difficult to cut the material and complex shape of the workpiece; no cutting force when processing; no burrs and knife marks and other defects; tool electrode material is not harder than the workpiece material; direct use of energy processing,
