Wire EDM is a method to cut conductive materials with a thin electrode that follows a programmed path. The electrode is a thin wire. Typical diameters range from .004"-.012" although smaller and larger diameters are available. The hardness of the work piece material has no detrimental effect on the cutting speed. There is no physical contact between the wire and the part being machined. Rather, the wire is charged to a voltage very rapidly. This wire is surrounded by deionized water. When the voltage reaches the correct level, a spark jumps the gap and melts a small portion of the work piece. The deionized water cools and flushes away the small particles from the gap.

Emmie Die and Engineering is equipped with a Sodick 320D submersible wire EDM, which is capable of a 10 degree standard taper. The maximum table travel of 12" x 8.5" x 6" thick. It has a maximum work piece dimensions of 30" x 23" x 6".
