Development of Spindle Dynamic Rotation Accuracy Test System

In this paper, the high-speed electric spindle is taken as the research object. It start from the definition and test method of dynamic rotation precision, the dynamic rotation precision is deeply analyzed. After analysis we decided to measure the dynamic rotation accuracy of the high-speed electric spindle by the bidirectional measurement method suitable for the subject. The detailed formula of the mathematical statistical error separation technique used in the test process was deduced, and the complete flow of the dynamic test of the dynamic rotation accuracy was obtained. On the basis of the existing electric spindle of the laboratory, the necessary sensors and data acquisition cards are selected as needed to form the hardware part of the test system. Based on Qt, the test software is developed to build a stable, reliable and high precision The electric spindle dynamic rotation accuracy test system was tested and verified, and the obtained results were in line with the actual situation. The test system built in this thesis provides theoretical basis and technical support for the performance analysis of the electric spindle.
