| Abstract: | The dynamic errors and thermal deformation of motorized spindle are important indexes that can influence the accuracy of CNC machine tools, with a particularly significant impact on the positioning accuracy and the surface quality of the workpiece. The dynamic errors and thermal deformation of 150MD24Z7.5 motorized spindle are researched by Spindle Error Analyzer. Through the data analysis of the test results, synchronous error, asynchronous error, thermal equilibrium time and thermal deformation of different directions of the spindle in different speeds are obtained. The experiment results provide the accurate data to support dynamic error compensation and the intelligent prediction of thermal deformation of the spindle. |
