In this paper，the spring jacket and universal dividing head are used to clamp the components， and the 40Cr stainless steel positioning rod is milled in small batch by using conventional method. Reasonable milling parameters and cutting tool materials are selected according to the milling requirements of the components to ensure the qualification rate， size requirements and surface roughness of parts， thereby successfully completing the milling task of these components. With certain practical significance， this study also provides reference for milling of similar components in the future.
