【Abstract】 Based on the analysis for internal heat sources of high-speed spindle system on NC precise lathe,the finite element model of the 3-dimension stable temperature field of spindle system is established in the ANSYS/Thermal module,and the temperature field is calculated. The result of calculation can estimate the temperature distribution and rise of every part when the system is in the stable state. The curve of the spindle and the headstock’s highest temperature rise and rotational speed is gained by fitting ,and it can be used to estimate the highest temperature rise of the spindle and the headstock when the spindles rotates at different speeds,and provides technological support to improve the struture of the spindle system.更多还原
