Now the mould cavity EDM electrode material is the most widely used
Its requirements must be CHRAMILLES copper electrode spark line standards, if the use of other equipment or electrode processing of spark patterns are strictly unqualified
The most common is the copper electrode (copper and copper), large cavity molding or rough common graphite, but require a higher surface texture or special requirements is what is the processing of copper electrode (such as Matt NOKIA appearance of mobile phone lines,
Copper and pure copper.In addition, larger cavity molding is often done with graphitePrecision machining is useful to tungsten, molybdenum, etc., but very few"
