Electric Discharge Machining (EDM): High-Precision Machining for Hard Materials
What Is EDM?
Electric Discharge Machining (EDM) is an advanced manufacturing process that removes material from electrically conductive workpieces using controlled electrical discharges (sparks). Unlike conventional cutting, EDM does not rely on mechanical force, allowing precise machining of extremely hard materials, intricate shapes, fine cavities, and complex geometries. EDM is commonly used in aerospace, automotive, mold making, tool and die, and medical industries where precision, surface quality, and tight tolerances are critical.
主要特征和优势
High-Precision Material Removal – Capable of tolerances as tight as ±0.01 mm for intricate components.
Works with Hard & Conductive Materials – Ideal for tool steels, titanium alloys, tungsten carbide, and exotic metals.
Complex Geometries – Produces deep cavities, narrow slots, sharp corners, and fine holes down to 0.1 mm diameter.
Two Main EDM Methods:
Sinker EDM – Uses electrode tools to create cavities, pockets, and detailed features.
Wire EDM – Uses a thin wire (0.02–0.3 mm) to cut precise contours and profiles.
Excellent Surface Finish – Surface roughness Ra 0.4–1.6 μm achievable with minimal post-processing.
Non-Contact Process – Reduces mechanical stress, distortion, and tool wear.
