  • Electrical Discharge Machining (EDM)
    Electrical discharge machining (EDM) uses the discharge from an electrode to cut metal. There are two main types of EDM: wire and ram. With wire EDM, the electrode is a thin wire typically made of brass or other alloys. With ram EDM, the electrode is a specially shaped piece of graphite or copper
  • Copper EDM Electrodes
    EDM electrodes and materials (wire or tube) are used in (EDM), a process that removes metal with an electrical discharge of very short duration and high current density between the electrode and the workpiece. Copper is often used to manufacture electrical discharge machining (EDM) electrodes
  • EDM Boosts Form Tool Industry
    ., 10 employees, and a solid clientele primarily serving the automotive parts industry. The company has been in its current building for six years. "Electrical discharge machining revolutionized the form tool business," Hoskins declares. "Back when all the tooling was high speed steel, we used surface
  • Advanced Manufacturing: Rapid Roughing of Tough Materials
    , and engine complexity. Blisks are usually roughed-out by CNCs, electrochemical milling (ECM), or electrical-discharge machining (EDM), and then hand polished. A more recent and faster roughing approach comes from so-called "blisk" machines that combine processes similar to ECM and EDM

    . of the oil fi lm layer in the bearing, shaft current. discharges, causing electrical discharge machining. (EDM) pits and fusion craters in the race wall and ball. bearings. This phenomenon continues until the bearings. become so severely pitted that fl uting, excessive. noise, and failure occur
  • Medical Device Link .
    , miniature three-dimensional (3-D) metal structures that are impossible or impractical to make using other technologies such as electrical discharge machining (EDM), laser machining, or silicon micromachining. This article describes how the new technology process works, compares it with other technologies
  • Improved HCF Performance and FOD Tolerance of Surface Treated Ti-6-2-4-6 Compressor Blades (.pdf)
    thermal exposure to 371C. Blade-edge bending fatigue specimens were. designed to simulate the leading edge of an. integral bladed rotor (IBR) compressor blade. FOD was simulated by controlled size notches. introduced on the specimens using electrical. discharge machining (EDM). Both disk and blade
  • Medical Device Link .
    precision machining, micromolding, electrical-discharge machining (EDM), laser processing, and a range of lithographic and electrodeposition methods can all be used to help medical companies create very small or high-precision parts and assemblies to solve a variety of design and manufacturing
