The five-axis machine tools for large area machining is designed and developed by R&D center of NAMSUN. For high precision machining, the thermal characteristics of spindle system have evaluated by using ANSYS program. The heat sources of the spindle were a stator, a rotor and two bearings. The heat generation rate and the heat transfer coefficient also were calculated. The maximum temperature and the thermal deformation were 22.5℃ and 35.6㎛, respectively.
