PURPOSE:To prevent uneven pressure on guide faces as well as partial contact between a moving body and guide faces by providing a slide-guiding face for a dynamic pressure as one of a pair of opposite slide guiding faces of a machine tool and for a static pressure as the other. CONSTITUTION:A grinder axis housing 101 is guided by columns 102, 103 and makes a vertical motion by a feed screw 104. A static pressure guide board 105 is connected with the grinder axis housing 101 by a bolt. As regards the C direction, a pair of static pressure guide faces 207, 208 is provided in opposition to a pair of dynamic pressure sliding guide faces 205, 206. Thus, a pair of dynamic pressure sliding guide faces 205, 206 is the only standard of movement, while the static pressure guide faces 207, 208 perform equalized pressure distribution in guide faces 205, 206. |
