Ram EDM Machines

Ram electrical discharge machining (EDM), also known as die sinking, uses an electrode typically pre-machined to a specified shape from graphite or copper that is sunk into a workpiece submerged in a dielectric fluid, leaving a negative imprint. A controlled spark discharges in the small gap between the workpiece and electrode to erode and remove material through melting or vaporizing. Ram EDM can cut any material that is conductive, including parts made from tungsten carbide or titanium that are hard to machine, and produce shapes and depths that are impossible to reach with a cutting tool. It produces surfaces with a fine finish and high precision that are ideal for complex die and moldmaking used in the automotive and aerospace industries.
