Abstract: Spherical grinding machine of this subject is a precision machining of spherical grinding wheel for grinding machine. The method of high precision and efficiency of compact structure.The workpiece can be automatically and continuously finish surface grinding in a fixture, precision grinding machine is suitable for the sphere. In this paper, firstly, introduces the current situation of the development China sphere grinding machine technology, expounds the purpose and significance of this research design. In summary and reference to various domestic and foreign spherical grinding machine, designed the scheme. This design is a kind of precision machine tool with high precision tilting rotary table. High precision swinging type rotary table is mainly used for processing the three-dimensional sphere. It can freely rotate and swing, swing and swing by two kinds of movement to complete the processing of sphere. In this paper, through the design of precision worm gear design precision and swing mechanism to control parts, machining precision.
