EDM has always played an important role as an industrial technology in mould processing area.
Advantages of Duratight EDM graphite electrode
1.Little weight: About 1/5 of cuprum that largely cut down the load of the EDM.
2.High speed of electrical discharge processing (about 1.5~3 times of cuprum).
3.High density, low rate of abrasion.
4.Low coefficient of therml expansion.
