Abstract：

The processing quality of work pieces and service life of die were directly impacted by the operation and maintenance level of NC turret punch press die. Therefore, the principle, structure and its basic knowledge of NC turret punch press die were introduced, and the selection principle of standard die and forming die were emphatically expounded. Then, the causes of material sticking, die wear, scrap rebound, stamping noise and dislocation of upper and lower dies in the using process of NC turret punch press die were analyzed, and then the solving measures were put forward. Finally, the technical points to follow in the operation and maintenance process of NC turret punch press die were given from many aspects of die clearance, die edge sharpening, die lubrication, die cleaning, die repair,etc. in order to guide enterprises and users to correctly and rationally operate and maintain dies and meet the actual production requirements.
