ことができる。(Prior art) This type of static pressure slide table is provided with a reference guide integrally attached to the bed, and the reference guide guides and supports the table so as to be able to reciprocate in the longitudinal direction via a first static pressure slide device. According to such technology, the table is guided and supported by the bed so as to be slidable back and forth in the longitudinal direction, and the table is reciprocated by a feed screw via a static pressure joint that is floatingly connected to the table. The static pressure slide device reduces the sliding resistance of the table guide support and improves rigidity, and since the table is reciprocated via a floatingly connected static pressure joint, there is no possibility of bending or eccentricity of the feed screw. No force other than the feeding force due to errors in installation with respect to the reference guide is applied to the table, and therefore feeding accuracy can be improved.

るものである。In such conventional technology, the guide rail for the static pressure joint is provided separately from the reference guide, which complicates the structure and increases manufacturing costs.The relative error between the guide rail and the reference guide also reduces the feed accuracy. There is a risk that the
Furthermore, since the static pressure joint is provided near one end of the table, there is a problem in that the feeding accuracy varies depending on the feeding direction. The present invention solves these problems by guiding and supporting the static pressure joint using a reference guide that guides and supporting the table, and by arranging the static pressure joint symmetrically with respect to the center of the table.

）を設ける必要は必ずしもない。When the servo motor 45 operates, the feed gear 41 is driven to rotate, and the static pressure joint 30 supported by static pressure on the reference guide 41 is rotated.
is reciprocally driven via a nut 42, and the table 20, which is also statically supported by the reference guide 41, is reciprocally driven by the static pressure joint 30 via a hydrostatic thrust device 35,35. Therefore, the static pressure thrust device 35.35 is connected to the static pressure joint 3
The table 20 is configured to transmit only the longitudinal thrust of 0.
Since the force in the direction perpendicular to this is not transmitted, the feed direction applied to the static pressure joint 30 due to bending or eccentricity of the feed screw 41, installation error with respect to the reference guide 11, or installation error of the screw 42, etc. No other irregular forces act on the table 20, and the table 20 and the static pressure joint 30
Since both of them are guided and supported by the common reference guide 11, there is no relative positional error between them during sliding, and therefore the feeding accuracy is greatly improved. Further, since the static pressure thrust devices 35, 35 between the table 20 and the static pressure joint 30 are provided symmetrically with respect to the center of the table 20, the same feeding accuracy can be obtained in both reciprocating feeding directions. In addition, since the static pressure joint 30 is precisely restrained from movement in directions other than the feed direction by the second static pressure thrust device 32, only 45 servo motors are required as the bearing 43 that pivotally supports the feed screw 41; However, it is not necessarily necessary to provide a bearing (not shown).
