As the demands for precision parts in automotive industry increase, the grinding machine tool is thought to be more and more important. Generally, the run-out of grinding machine tool is less than 1 micron. The hydrostatic journal bearing, for its high stiffness and high damping characteristics, is widely used in grinding wheel spindle to achieve the desired accuracy. And for the accurate measurement of the rotating spindle, the capacitance type gap sensor which can measure the pure rotational vibration without geometrical error of the spindle is developed. In this study, we have analyzed grinding machine tool spindle supported by hydrostatic journal bearing and measured the run-out of this spindle with capacitance type gap sensor. To increase the stiffness, double pad diaphragm control valve has been used. And the grinding machine tool spindle with this type sensor can be applied in various rotating shaft.
