Wire EDM, also known as slow wire cutting, is a CNC machining center that uses a continuously moving thin metal wire (typically copper wire, referred to as electrode wire) as the electrode to perform pulse spark discharge on the workpiece, generating temperatures above 6000 degrees Celsius and eroding the metal to shape the workpiece. The principle of slow wire cutting is the phenomenon of continuous discharge to remove metal, due to the presence of a gap between the online electrode and the workpiece.
