What is wire EDM?<\/h3>\r\n

Wire EDM, also known as Electrical Discharge Machining (EDM), is a non-mechanical CNC-machining process used to accurately cut electrically conductive materials. Instead of applying cutting forces, we remove material through controlled electrical discharges. <\/p>\n

During the Wire EDM process, a thin continuously fed wire, typically brass, follows the programmed contour of the part. Thousands of electrical sparks occur per second between the wire and the workpiece. These sparks generate very local peak temperatures up to 20.000 degrees Celsius, causing microscopic portions of material to melt and evaporate. The energy is immediately dissipated by the dielectric fluid, limiting thermal influence on the surrounding material. <\/p>\n

Because Wire EDM operates without mechanical contact, there are no cutting forces acting on the part. This makes the process highly suitable for machining hard, hardened, or difficult-to-machine materials such as tool steel, carbide, and titanium. Wire EDM also enables the production of complex geometries, sharp internal corners, and fine details with high accuracy and repeatability. <\/p>\n

Wire EDM is widely used in precision engineering, tooling, machine building, med-tech industry and high-tech applications where dimensional stability, accuracy, and process control are critical.<\/p>\n

This gives several key advantages:<\/h5>\n
