Precision die processing is an effective method for enterprise's mechanical die processing. Compared with the traditional processing technology, it adopts the procedure of reducing the number of loading and operating steps of the workpiece. In addition, it keeps the orientation and process manufacturing. However, in order to ensure the precision of die processing, improve the quality of production and reduce production costs, it has strong oxidation, but also shows the following characteristics:

Firstly, there is a lower resistance to deformation and a certain range of temperature.

Thirdly, the quality requirement of grinding wheel and the unstable cooling environment are not easy to damage and crack.

Fourth, the high and balanced surface strength of quenching.
