Wire electrical discharge machining, also known as slow wire EDM, is a numerical control machining center that uses a continuously moving fine metal wire (referred to as electrode wire, usually copper wire) as the electrode to discharge a pulse spark on the workpiece, generating temperatures above 6000 degrees Celsius, and eroding and cutting the metal into the desired shape. The principle of slow wire EDM is the continuous discharge phenomenon that occurs between the online electrode and the workpiece, resulting in the removal of metal through a gap.
