Has been fully CNC lathe integrated production line.

At present, the professional manufacturers of domestic production punch precision can reach ± 0.002mm, living in the international leading level. HL blade professional processing: CNC tower factory punch, Chong mother, punch rod, punch nuts to maintain the accuracy between ± 0.002mm. Using a wide number of 980 CNC punch, Chong mother specializing in the production workshop. High quality, fast efficiency and so on.

The punch used to mold the workpiece when the lubricating oil is between the punch and the workpiece comprises a straight portion at its end and a diameter increasing portion. The straight portion includes an end face and a side face at its end portion. The straight portion extends in the axial direction. The end face extends in a radial direction perpendicular to the axial direction. The side is connected to the end face. The diameter increasing portion is connected to the straight portion. The width of the diameter increasing portion in the radial direction at the connecting portion between the straight portion and the diameter increasing portion is the same as the width of the straight portion. The width of the enlarged diameter portion in the radial direction increases as the distance from the straight portion increases. At least one of the end face and the side of the straight portion is formed with pits.
