Abstract	The deformation of hydrostatic bearing rotary workbench is the direct factor that affects working accuracy. In this paper, taking the hydrostatic bearing rotary workbench as research object, the improvement model of the hydrostatic bearing workbench structure is established. In different speed conditions, thermal deformation calculation for workbench is conducted by using finite element method and fluid solid coupling technique. By comparison of the results of the model before and after the improvement, it is concluded that the thermal deformation of the workbench can be decreased if we add rib plate appropriately. Conclusion can provide guidance for the production of the hydrostatic bearing workbench, and it also has certain scientific significance to improve the accuracy of CNC machine tools.
