Slow wire is a kind of CNC machining that uses continuous moving thin metal wire (called wire electrode, generally copper wire) as electrode, pulse spark discharge on workpiece, high temperature above 6000 degrees, metal removal and workpiece cutting. machine tool. The principle of slow wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is continuously discharged to remove the metal.

Since the wire-cutting machine adopts the method of continuously supplying the wire electrode, that is, the wire electrode is processed during the movement process, even if the wire electrode is worn out, it can be continuously replenished, so that the machining accuracy of the component 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, linear error and dimensional error of the slow wire cutting machine are much better than those of the wire cutting machine, so it is processed. Slow-wire cutting machines are widely used in high-precision parts. In addition to early SMEs, it is also very common in processing plants in large companies such as aerospace, automotive, and medical. Kunshan slow wire
