Can make the local metal melting, oxidation and corrosion, thus creating and invented the EDM processing methods.
Wire Cut Electrical Discharge Machining (WEDM), is an area of electrical processing, is the former Soviet Union Lazarindo couple research switch contacts spark damage caused by the phenomenon and causes of corrosion, found that the instantaneous high temperature spark
Today, WEDM has accounted for more than half of EDM machines.
It not only makes the application of EDM developed, but also has replaced some aspects of EDM perforation, forming processing.
It is in the spark of perforation, forming the basis of the development of processing.
