【Abstract】 Taking the spindle of CX8075 vertical machining center as example,the thermal boundary conditions were determined,the heating value was calculated and 3D digital model of the spindle was established as well.Then the distribution of temperature field was studied by ANSYS and thermal deformation of spindle was obtained.Afterwards the reasons of thermal deformation were analyzed,which laid a theoretical basis for error compensation of thermal deformation of the spindle.更多还原
