Wire EDM

EDM (Electrical discharge machining) is a manufacturing process of creating a desired part from the metal part by using electrical discharges (sparks). Wire EDM, also known as wire electrical discharge machining (WEDM) or wire-cut EDM, involves using a thin single-strand metal conductive wire, like brass, along with de-ionized water/kerosene allows the wire to cut through metal with the heat from electrical sparks. The wire EDM can be used to cut very deep, narrow feature which is very difficult for the milling cutter to machining, the requirement for the narrow/deep feature is: it has to be a through feature(blind hole can be machined by wire EDM).
