Abstract
The dynamic and thermal characteristics of spindle assembly will affect the final machining performance of a machine tool seriously. It is of great significance to study the dynamic and thermal characteristics of the spindle assembly for improving the level of machine tool's design and manufacturing. The paper takes a high precision computer numerical control lathe as the research object. First the thermal characteristics were obtained by using finite element method. Then the laser triangle measuring instrument and the infrared thermal imager were used to measure the temperature field and thermal deformation of the spindle assembly. Finally in order to get the thermal equilibrium time and the thermal deformation data of spindle system, the wavelet toolbox was used to deal with thermal testing data. The paper's work laid a foundation for the further research on the thermal characteristics analysis and thermal error's compensation of machine tools.
