Wire Erosion or Electrical Discharge Machining (EDM) is a process we use daily at GoTools. Essentially it is an accurate and efficient way to cut hard metals that are difficult to machine using traditional methods. Tungsten Carbide, Hardened Steel, Titanium, Waspaloy, Nimonic, Nitralloy, Stellite are examples of metals that can all be machined with our Mitsubishi MV1200R Wire-cut EDM.
