A study on the thermal characteristics and experiments of High-Speed spindle for machine tools

Based on the finite element method and thermal analysis, a study on the thermal characteristics and experiments of a 40,000 rpm high-speed spindle for machine tools are carried out. In this study, finite element analysis for the spindle system is carried out to obtain the temperature distribution, temperature rise and thermal deformation of the spindle system as affected by different rotation speeds. And then through vibration test, the relationship between thermal deformation and vibration during rotation of the spindle was tested and analyzed. By comparing the calculated results with experimental results, the accuracy of the model was verified. This provides the basis for design of the high speed spindle system.
