Axial enlarging work method, which has been developed on the basis of mechanical ratchet phenomenon over long years, has great merits of being green for environment as well as saving energy and resources. The plastic forming works to enlarge partially a long round bar at nearer position from the bar end would be expected as one of novel axial enlarging technologies. Some difficult matters of how to apply axial compressive force to a long round bar and how to avoid buckling deformation occuring during axial enlarging process could be resolved theoretically considering a significant model analysis, which could determine a suitable process loading condition for axial partial enlarging plastic working without occurring some buckling plastic bends, and so a new axial enlarging machine for a long shaft was successfully developed to form a near net shape of a long round shaft with a boss, which can be manufactured into a ball screw part.
