The idea of the hydrostatic thrust bearing pose control was presented to improve NC machine tool precision. The bearing worktable poses by controlled by coupling oil film thickness of 4 controllable chambers. The chamber flow can be regulated by variable pump. The flow of the variable pump was controlled by electro hydraulic servo valve according to the surface roughness, load, cutting force, and thermal effects of worktable. The mathematical models of the controllable chamber flow. The pose control model was established, which contains the kinematics positive and negative solution. The simulation experiment was carried out on the electro hydraulic servo test bench. The experiment results show that the model of hydrostatic thrust bearing pose is reasonable and control scheme is effective.
