In recent years, the rapid development of the national precision instrument industry, and precision mold processing are used in these precision instruments, electronic products, machinery, mold, and so on, which, in the field of medical machinery, automotive, aerospace and other areas of development is relatively strong. However, these precision mold processing technology is difficult, the precision of the process requirements is higher, the added value of the processing chain, and higher profit margins, etc.. Multi station progressive die production requirements have some characteristics: coordination difficulty, high cost, long time, long service life, high dimensional stability, high wear resistance, high strength, high hardness and so on three key parts
      In the face of these problems, we should introduce some high precision cutting machine tools, change the thickness, eliminate the bad effects, from the workpiece, the standard process, double wire technology and other aspects of comparison, reduce the roughness of some process surface, achieve high precision, high quality, high efficiency of precision mold processing efficiency.
