![]() This is possible with wire diameters as small as. The technology allows for equipment even from the early 2000s, to go down to. ![]() ![]() This has kept pricing relative competitive over the years.Įlectrical discharge machining is particularly known for amazing accuracy. Wire EDM machines are made by a wide range of manufacturers like Sodick, Sharp, Makino, Charmilles, Agie, Mitsubishi, Kent, Brother, Perseo-Eri, Belmont, Aneutronic, Sunwind and more. New machines by Mitsubishi, like the MV1200-S for example, have 45 degrees 1.8 wide angle taper options. Early models of EDM were for die making, and a 1-degree die relief to 4 or 5 inches used to be the maximum possible taper. The machine travels should be listed for any used EDM machine. Dimension on all axes have increased, but now you can get machines with much more z-axis. When selecting a wire EDM machine, youll notice that newer machines come in a wide range of sizes. Water flushes away the debris for a very clean saw-like cut.Ĭutting speed has increased as technology has advanced over the years because of higher flushing pressure and faster solid-state generator circuitry, among other things. ![]() The parts are submerged in deionized water and the wire acts as the electrode. It uses a single string of thin metal wire for precise incisions in thick metals. Wire EDM machines have advanced since the 1970s when it was first introduced in speed, workpiece size, taper, price, accuracy and with EDM machines, unattended operation abilities. ![]()
