Slow Wire Cutting, also known as Low-Speed Wire Cutting, is a CNC machining center that uses continuously moving fine metal wire (referred to as electrode wire, usually copper wire) as the electrode to perform pulse spark discharge on the workpiece, generating temperatures above 6000 degrees Celsius and eroding the metal to cut into the desired shape. The principle of Slow Wire Cutting is the continuous discharge to remove metal that occurs between the online electrode and the workpiece due to the existing gap.
