Abstract

PURPOSE:To enable precise feeding which is not subjected to thrust by bearing a nut housing through first and second static pressure bearings in axial and rotary direction with respect to a moving body and base, and varying the gap of the second static pressure bearing through hydraulic pressure corresponding to variation of the gap of the first static pressure bearing. CONSTITUTION:A housing guide rail 1b is laid on the underface of a nut housing 5, and a moving body 2 is mounted movably on the slide guide face 1a of base 1 through a static pressure bearing. Static pressure pockets 5b, 5c and 5e, 5f corresponding to the guide rail 1b are arranged respectively on the underface and upper face of the nut housing 5, then pressure oil is fed through oil paths 2b, 2c to the static pressure pockets 5e, 5f. Furthermore, pressure oil in the static pressure pockets 5e, 5f is fed through throttles 5g, 5h to the static pressure pockets 5b, 5c. Consequently, micro amount turning control can be made without being subjected to thrust force.
