What is WEDM?

Wire Electrical Discharge Machining (WEDM), also known as wire EDM, wire cutting, or spark erosion, is a machining process that uses electrical discharges (sparks) to cut a desired shape out of electrically conductive materials. A thin, charged wire, typically made of brass or other suitable material, acts as the cutting tool. The workpiece is submerged in a dielectric fluid, which helps to flush away debris and control the spark. WEDM is commonly used to create intricate shapes and tight tolerances in materials that are difficult to machine using traditional methods. Applications include tool and die making, prototyping, and manufacturing of precision parts.
