What is Electrical Discharge Machining (EDM)?

Electrical Discharge Machining (EDM) is a precision process that removes metal by controlled electrical sparks. A high-frequency current generates spark discharges between a tool electrode and the workpiece, submerged in dielectric fluid. This allows material shaping without direct contact or cutting forces.

EDM is ideal for machining hard metals like steel, titanium, and carbide that are difficult to cut with traditional methods. It is commonly used for crafting injection molds, stamping dies, and other complex shapes that cannot be easily produced using conventional machining techniques. The technology excels in drilling fine holes, cutting intricate profiles, and creating sharp internal corners.
