As the spark jumps across the gap, material is removed from both the workpiece & the electrode. “The price of a wire EDM machine is nothing compared to the cost of wire over the life of the machine,” says Tom Frick, owner of Intricate EDM in Columbia, Pennsylvania. An electrical discharge (spark) is created on a conductive wire, typically brass, that will pass through the given material giving it a … Wire EDM machining (Electrical Discharge Machining) is an electro thermal production process in which a thin single-strand metal wire in conjunction with de-ionized water (used to conduct electricity) allows the wire to cut through metal by the use of heat from electrical sparks. To begin the cut, the wire must cut into the metal from the side, or through a hole that is drilled into the center of the metal. Headland exclusively represents the Makino range of wire EDM machines in Australia. The Ecyclopædia Britannica gives a short explanation of EDM:“EDM involves the direction of high-frequency electrical spark discharges from a graphite or soft metal tool, which serves as an electrode, to disintegrate electrically conductive materials such as hardened steel or carbide.”To put it more simply, electrical discharge machining is a manufacturing process that precisely removes material from conductive materials using an electrode. In wire EDM machining, the material is removed from the workpiece by a series of rapidly recurring current discharges between the wire or the electrode and the workpiece, they are separated by a dielectric liquid. Wire EDM is a form of machining which is done using a thin wire that can cut in any X,Y,U,V direction. Laser.

How does Wire EDM work? It is capable of some incredible things that cannot be done using any other machining process. A spark jumps from the electrode to the work piece and disintegrates the steel with a controlled electrical charge. It uses an electrically charged thin brass wire, which is moved by computer control, close to, but not touching, the part to be cut. Material is removed from the work piece by a series of rapidly recurring current discharges between two electrodes, separated by a dielectric liquid and subject to an electric voltage. After the parts are EDMed, a non-contact video inspection system, interfaced with a computer system, automatically examines the work. As the spark of electricity jumps between the space of wire and work piece, it removes material and slices through the piece. R&D Investment Ensures New Zealand Tube Mills' Success. EDM is an unconventional method that does not require mechanical force during the removal process, uses a single thin wire, and uses the heat generated by electric sparks together with deionized water to cut the metal, the cutting wire does not touch the material, and prevents rust.
