Abstract: The part"chuck"original workpiece in this article is defined as powder metallurgy mold piece. Due to the complexity of the part and high demand of the shape, size and position degrees, the price is high, and the accuracy can not meet the requirements if it is produced in do?mestic;Therefore, the powder metallurgy mold piece is replaced for machining materials (Nitriding steel)for process. The bottom residual mate?rials of the"9-R13+0.4"arc gap on the machining piece can't be removed, however, through the design and manufacture of cold punching mould, this problem can be solved, to ensure the chuck size precision and positioning requirements, developing a new way of process for the subse?quent new products'research and development.
