Electrical Discharge Machining (EDM)

Electrical Discharge Machining (EDM) is a manufacturing process that uses controlled electrical sparks to precisely erode material from a metal workpiece. When a conductive electrode approaches the metal closely, a series of rapid electrical discharges occur across the gap, melting and vaporizing small amounts of metal. This process is controlled by computer, allowing for the creation of complex shapes and fine details that are difficult with traditional machining. EDM is especially useful for working with hard metals and materials that are tough to cut by conventional means, producing precise, high-quality components through an erosion process rather than mechanical force.
