[0002] Wire-cut cutting machines, as essential tools in precision machining, are widely used in industries such as mold manufacturing, aerospace, automotive manufacturing, and electronics, where workpiece precision and surface quality are extremely demanding. Their operating principle is to utilize a continuously moving metal cutting wire (such as molybdenum or copper) as a tool electrode, eroding the workpiece material through electric spark discharge, achieving high-precision cutting. However, key factors affecting wire cutting quality and efficiency have always been wire tension control, current conduction stability, and cutting accuracy.
