Tóm tắt

For the hard and brittle materials like optical glasses, ultra-precision grinding machine is primarily used, which can generate parts with high surface finish, high form accuracy and surface integrity. Motorized spindle is an inevitable choice of ultra-precision machine, but it has a prominent heat problem for its specific configuration of build-in motor. The paper does some research about motorized spindle thermal property. The heat resources and heat transferring ways are analyzed. The temperature distribution and deformation distribution of motorized spindle system are calculated through thermal structure coupling finite element analysis. The analysis results can provide warranty for motorized spindle design.
