| Abstract: | In this paper, the supporting pattern of the ball screw pair in numerical control machine is antroduced, and the mechanical model under the gravity force when mounted horizontally is onalyzied. With these models, the mathematical expressions of the deformation value can be calculated and the deflection curve equation could be obtained. At the same time, the machining error caused by the gravity bending of the ball screw is evaluated. |
