CNC EDM
CNC EDM (Electrical Discharge Machining) is a non-contact machining process that removes material using controlled electrical sparks between an electrode and the workpiece. The process is capable of machining extremely hard materials that are difficult to cut with conventional tools. Two primary EDM methods: Wire EDM uses a thin wire to cut through conductive materials, producing precise profiles and shapes. Sinker EDM uses a custom-shaped electrode to create cavities and complex internal features. Wire EDM holds tolerances of ±0.005mm, sinker EDM holds ±0.01mm. Materials include hardened tool steels, titanium, carbide, Inconel, and other conductive materials. Common applications include precision dies, mold cavities, aerospace components, medical parts, and semiconductor equipment.
