Wire electrical discharge machining (EDM) uses a thin brass wire and controlled electric sparks to cut intricate profiles in electrically conductive materials like metals with precision and little burr formation. It can cut hardened materials and complex geometries more economically than traditional machining. The wire EDM process uses deionized water as a dielectric fluid to carry away debris from the cutting zone and produce smooth matte surfaces on finished parts with edges that require no further finishing. Wire EDM technology has advanced to allow faster cycle times and improved accuracies and surface finishes with strategic equipment investments.
