Manufacturing News – Wire EDM

Wire electrical discharge machining (EDM) is used to produce precision parts for many applications.

Using CNC controlled wire EDMs, you are able to program complex geometries and repeatedly produce precision parts with a high level of accuracy. Wire EDM is a non-traditional method of removing material by a series of rapidly recurring electrical arcing discharges between an electrode (the wire) and the work piece. The machine’s DC-charged thin brass wire can slice through any electrically conductive material, including difficult-to-machine metals such as hardened tool steels.

Electrical Discharge Machining will only work with materials that are electrically conductive and generally those materials are ferrous alloys. The wire-cut process uses water as its dielectric with the water’s resistivity and other electrical properties being carefully controlled by filters and deionizer units. The water also serves the critical function of flushing the cut debris away from the work piece.
