What is EDM (electrical discharge machining)?
Quick answer: EDM removes conductive metal with carefully controlled electrical sparks rather than a conventional cutting edge.
EDM removes conductive metal with carefully controlled electrical sparks rather than a conventional cutting edge.
- The workpiece and electrode are positioned in a dielectric fluid.
- Electrical discharges erode tiny amounts of metal.
- The process forms intricate details in hard conductive materials.
- Wire EDM and sinker EDM serve different shapes and applications.
Good to know: EDM is common in mold-making, aerospace components, and medical instruments where ordinary tools cannot reach.
