Abstract
A punching die for bag making machine and method for same, where the cutting blade and the shank of the punching die are designed to be detachable and the blanks of the shank, cutting blade and die holder are lathed from different materials. The cutting blade and the die holder indent that are subject to heat treatment are integrally cut by wire cutting. The cutting end face of the cutting blade and die holder concave are then subject to polishing. This invention simplifies the manufacturing process, ensures precise accommodation between the cutting blade and the die holder concave, thereby simplifying the manufacturing process and reducing the cost.
