In this paper, the spindles thermal characteristics of CNC milling machine in steady state and transient state are analyzed by using ANSYS, the temperature field and thermal deformation field are obtained. After a number of tests are done in different working conditions, the temperature and thermal deformation changes of spindle are measured in every working condition. Combing the FEM analysis with tests results, the thermal deformation of spindle from starting to reach thermal balance on CNC milling machine is discussed, some suggestions are presented to improve the process precision of CNC milling machine.
