Broken wire and cause of CNC wire cutting machine
Recently, CNC wire-cutting machine tools have been widely used by the machining department to realize automatic cutting of various shapes of die and parts. This processing method has the advantages of high precision, high speed, and short cycle. Wire cutting machine tools are the success of mechatronics in metal cutting machine tools. However, the machine tool also has unsatisfactory use in use. The more prominent one is the broken wire problem. Broken wire not only wastes expensive molybdenum wire, but also causes the scraped workpiece to be scrapped. Generally, a coil of molybdenum wire (for example, φ0.14mm) should be
