Bradford also offers Electrical Discharge Machining (EDM), an innovative manufacturing process. EDM uses electrical discharges to cut and drill incredibly complex and precise shapes into any electrically conductive metal. This process easily achieves tolerances of -.0002″, provides excellent finishes up to 8 RMS, and leaves no stresses or burrs in the material. Parts such as precision gauges, keyways, gears, splitting tubes, internal splines, and cams are perfect for this process.
