ブル送り装置。 In the table feeding device, a feed motor applies relative rotation between a nut and a feed screw screwed thereto to feed a slide table supported statically on a fixed base by a hydrostatic pressure bearing, wherein the fixed base A sub-table on which the nut is fixed is placed so as to be able to slide in the same direction as the sliding direction of the slide table, and a fluid supply pipe to the hydrostatic bearing is connected via this sub-table. At the same time, this sub-table is connected to the slide table via a coupling member supported so as to be floating in the sliding direction of the slide table using a static pressure bearing having lower support rigidity than the hydrostatic pressure bearing. A table feeding device featuring:
