The present situation of high-precision aerostatic spindle rotation accuracy testing was summarized.The test-bed for aerostatic spindle rotation accuracy which was independently designed was introduced.The test-bed comprised test-table,self-aligning components,flexible coupling,displacement sensor,master ball and motor.Then the test-bed’s composition,structure and test method were introduced.The designed test-bed provides a reference for high-precision aerostatic spindle rotation accuracy testing without drive or encoder.
