Slow Wire EDM, also known as Low-Speed Wire EDM, is a CNC machining center that uses continuously moving thin metal wires (referred to as electrode wires, typically copper wires) as electrodes to perform pulse spark discharges on workpieces, generating temperatures above 6,000 degrees Celsius, eroding metal, and cutting the workpieces. The principle of Slow Wire EDM involves the phenomenon of continuous discharging to remove metal due to the existing seam gap between the online electrode and the workpiece.
