E lectric D ischarge M achining or EDM is a process that uses electrical sparks to erode metallic work-pieces. It uses an electrically charged thin brass wire, which is moved by computer control, close to, but not touching, the part to be cut. How Does Wire EDM Work? … “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. When the two are close, the electric current is generated by the electric current to melt the gap. Located near Pittsburgh, we draw on a tradition of excellence and service that has been part of the nation’s metal-working heartland since the dawn of American manufacturing. Anywhere there’s a need for custom tools for complex geometries and hard-to- machine materials, count on us for fast and responsive service. As the spark jumps across the gap, material is then removed from the work piece and the electrode. Headland Stock List Read more about the instant asset and depreciation write...

Our expertise is broad and deep, with skills that include CNC grinding, medical tool grinding, OD and ID grinding, and Wire EDM. Electrical discharge machining (EDM) is a critical tool for many modern manufacturing applications that has evolved over decades of use. Wire EDM is a form of machining which is done using a thin wire that can cut in any X,Y,U,V direction. The special electrode enables the machine’s electric cutting spark to drill deep, angled holes in metal plates, hardened alloys, and … We are experts in the cutting tools industry. We continually invest in the latest equipment and inspection technology, and we monitor production against your requirements through every stage in the process. Wire EDM machining (also known as \"spark EDM\") works by creating an electrical discharge between the wire or electrode, & the workpiece. Because the wire is so fine, you can cut small-radius inside corners or even narrow slots. 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. This specific type of EDM uses a thin wire as an electrode to cut and shape solid metal pieces, and is often used for cutting solid steel. Paul Zupen – Engineering Manager, A & M Specialties, Inc. The cutting wire never touches the material, the cutting itself is due to the erosion that occurs when a spark forms between the cutting wire and raw material. 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. How does the small hole EDM process work? In order to keep the wire from burning up, one of our machines continuously The full name for the device is a “Wire-cut Electrical Discharge Machine.” The wire in this case is a long spool of very thin, coated brass wire. Makino is a world leader in CNC machining centres, high-precision metal cutting technology and EDM machinery, including horizontal machining centres, vertical machining centres, five-axis machining centres, graphite machining centres, and wire and RAM EDM’s. There is little change in the mechanical properties of a material in Wire EDMing due to its low residual stresses. Wire EDM can easily cut hard conductive material and produce complex parts with high precision. The Sinker EDM is used for projects that require complex shapes, while Wire EDM acts as an electrode, which is used to cut the workpiece. One of the electrodes is called the tool-electrode, or simply the tool or electrode, while the oth… We’re specialists in solid carbide, brazed carbide, high-speed steel, and other specialty materials. Wire EDM has no added residual stress because it has no cutting forces. Sinker EDM executes the shaping process using highly precise and pre-machined electrodes to create a negative of the workpiece by sinking it into the piece to attain the desired shape. There are two main categories: wire EDM and sinker EDM; each has a different application. Wire Electrical Discharge Machining (EDM) precisely cuts electrically conductive materials with a smooth finish and zero burrs. We pride ourselves in fast, reliable delivery as a standard practice, and are also equipped and staffed to provide expedited same-day service when needed. Do you need a CNC Milling Machine soonest to take advantage of... Second Hand STOPA Compact, Sheet Metal Storage Opportunity. “Wire is the single highest expense in operating a wire EDM. 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. EDM. Website by ProFromGo Internet Marketing. This field is for validation purposes and should be left unchanged. Milling. On the machining area, each discharge creates a crater in the workpiece and an impact on the tool. How Does Wire EDM Work? Not only does it determine the price of the work to be performed, it can also be a very useful tool for knowing your costs, scheduling the work through the shop, continuous … The electrode then makes an electrical connection with the steel. How does EDM Wire-Cutting work? The waste material is removed by the dielectric, and the process continues. Wire EDM machining works by creating an electrical discharge between the wire or the electrode and the work piece. For more than 40 years, Custom Tool & Grinding has been providing fast, accurate, high-quality custom cutting tools and grinding services to North American and global manufacturers who need standard and non-standard cutting tools. Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a metal fabrication process whereby a desired shape is obtained by using electrical discharges (sparks). Laser. This method is usually performed in a bath of water. EDM stands for “electric discharge machining.”.
