Abstract

PURPOSE:To compensate for a load acting on the inner surface of a base bed slide guide so that frictional slide force can be set, by controlling pressurized air supplied to a plurality of static pressure pads having gaps for pressurized air flow in no contact with a slide guide surface. CONSTITUTION:Air for a static pressure pad is supplied from an air pressure source 1 through a pressure controlling valve 12 to an air supply groove 13. A workpiece 14 is mounted on a slide 3, and the weight Wt of slide 3, weight Ww of workpiece 14 and cutting force F or the like acting on the workpiece 14 work on a dynamic pressure slide surface as surface pressure and a floating force Fp acting on the static pressure supplied to the static pressure pad crbitrary floating force is obtained, so that the share of dynamic pressure slide surface and static pressure pad can be set at will according to load requirements only by supplying air pressure to set optional frictional force.
