If this time using common lubrication guide rail, the friction is opposite bigger, especially the guide rail static and dynamic friction change will directly affect the processing quality and precision of the control, it is difficult to meet the numerical control technology requirements. Therefore, the static pressure guide is a kind of common machine tools design form. Because of the high rigidity, high precision, low wear technology advantage, static pressure guide has been widely used in the field numerical control machine. The stiffness of the static pressure guide rail, carrying capacity, and work capability directly influence the machining precision of the machine tool, to ensure the accuracy of guide rail is always in the most preferred to consider the factors. In the process of operation, the accuracy of the bearing capacity of guide rail with changes, sometimes even beyond the scope of the regulations, the bearing not only reduced the guide life, while also reduces the machining p
