CNC EDM (Electrical Discharge Machining) is a method of precision machining that uses an electrical discharge to erode materials from a workpiece. The process is controlled by a computer numerical control (CNC) system, which enables high levels of accuracy and repeatability in the machining process.

The main feature of CNC EDM is its ability to machine complex and intricate parts with high precision and accuracy. It is particularly useful for parts that require tight tolerances or have complex shapes, such as in the aerospace, medical, and automotive industries. Additionally, CNC EDM can be used with a wide variety of materials, including metals, plastics, and ceramics, making it a versatile option for precision machining.
