Abstract:
In order to meet the demand of thermal design of modern machine tools, thermal model and thermal characteristics of high-speed spindle system in numerical control(NC)precision lathe were studied in detail using finite element method(FEM). The results show that the system reaches a thermal balance after 3 h while it is rotating at 8 000 r/min and the highest temperature is located in the inner-ring of the front bearings. Furthermore, the thermal deformations of the spindle head were calculated. Through reasonable arrangement and optimal design of the fines, the radial and axial deformation of the spindle head can be reduced to less than 2 μm, which satisfies the demand of manufacturing accuracy. Especially, the radial deformation of the spindle head is around 1.55 μm, the optimization effect being remarkable.
