A study on the Error Separation Method in Rotation Accuracy Measurement of High Precision Spindle Unit

Kim, Sang-Hwa,Kim, Byung-Ha,Jin, Yong-Gyoo,


The rotation of a spindle unit must be accurate for high-quality machining and to improve the quality of the machine tools.Therefore, the proper measurement of the rotation accuracy and ensuring a proper analysis are very important. Separate processes are necessary because spindle errors and roundness errors associated with the test balls can both factor into the measured rotation error values. We used three methods to discern test ball errors and analyzed which could be deemed as the most proper technique in a test of the rotation accuracy of the main spindle of a machine tool.
