Abstract: The spherical grinding machine is a new, grinding, precision machine tools with high precision, the grinder that is efficient and compact, good prospects for the development of precision machine tools, they are generally spherical in the rear axle applications, workpiece clamping, can automatically and continuously complete spherical grinding, machine tool machining precision grinding balls. This paper describes the present situation of China the spherical grinding technology, describes the purpose and significance of the research design. On the basis of the domestic machine tool, through consolidation and learn to design the program. The design is by precision machines with precision swing rotary table. Swing precision rotary table formed mainly spherical. Then grinding wheel, processing sphere. By controlling design precision worm gear design accuracy and swing mechanism to control precision machining, process requirements.
Keywords: worm gear;the swing mechanism
