Why Bother With EDM Copper

Highly detailed electrodes, which were formerly manufactured on surface grinders, required many hours of highly skilled labor. The use of copper and WEDM to produce these electrodes has dramatically changed EDM machining. It is less likely to cause pits in the steel workpiece. The tendency of any electrode to "DC arc" is the curse of EDM.
