For studying the impact of the thermo-mechanical coupled deformation on precision of the experi-ment table, the CAD and FEA models of the ballscrews and the support of linear rolling guide were built on SolidWorks. Based on the analysis of heat conduction and forces,the temperature field and thermo-mechani-cal coupled deformation of ballscrews and support of linear rolling guide were calculated on SolidWorks Sim-ulation. The results show that the thermo-mechanical coupled deformation meet the accuracy requirement of the experiment.
