Low Speed Wire Cut, also called WEDM-LS, uses continuously moving thin metal wires (called electrode wires, usually copper wires) as electrodes to perform pulse spark discharge on the workpiece, generating a high temperature of more than 6000 degrees, which can erode metal and cut. A CNC machining machine tool that forms workpieces. The principle of slow wire machining is that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge.
Since the slow wire cutting machine adopts the method of continuous wire supply by the wire electrode, that is, the wire electrode completes the processing during the movement, so even if the wire electrode is lost, it can be continuously replenished, so the processing accuracy of the part can be improved. The surface roughness of the workpiece processed by the slow wire cutting machine can usually reach Ra=0.8μm and above, and the roundness error, straight line error and dimensional error of the slow wire cutting machine are much better than that of the fast wire cutting machine, so when processing When producing high-precision parts, slow wire cutting machines are widely used. In addition to early small and medium-sized enterprises, it is also extremely common in processing plants of large enterprises such as aviation, automobiles, and medical care.
