Electrical Discharge Machining (EDM) Spark Erosion is a highly precise machining process used to remove material from a workpiece by utilizing controlled electrical discharges (sparks). EDMspark erosion is ideal for producing intricate, complex, and delicate shapes, especially in hard, conductive materials that are difficult to machine by conventional methods. The process is particularly beneficial in industries such as aerospace, automotive, medical, and mold-making, where high precision, fine details, and tight tolerances are required.
Our EDM spark erosion services offer unparalleled precision and quality in machining, enabling the creation of parts with high complexity, detailed features, and minimal thermal distortion.
Process Description: Wire EDM uses a continuous wire electrode, usually made of copper or brass, to cut through the workpiece. The wire moves in a precise, computer-controlled path, guided by an electrical discharge. The material is eroded away in a controlled manner by the sparking process, allowing for the creation of intricate shapes, profiles, and features.
Machines Used:
- CNC Wire EDM Machines: These machines are equipped with automated controls that allow for precise cutting along complex contours.
- High-Speed Wire EDM Machines: For high-speed cutting with fine wire for ultra-precise cuts.
