Abstract:
1. A machine tool having a work moving in a Z axis direction on a stationary body section and a rotary spindle for machining the work, comprising: a pair of guide tracks extending in the Z axis direction on the stationary body section, an X axis direction intersecting the Z axis direction; a pair of feed tables guided by said guide tracks and movable independently; a support/feed/turn output member for supporting the work, the support/feed/turn output member being arranged between said feed tables so as to bridge said feed tables, the support/feed/turn output member being coupled with one of said feed tables to be relatively rotatable around a line in a Y axis direction which intersects both the X axis direction and the Z axis direction perpendicularly, and the support/feed/turn output member being coupled with the other of said feed tables to be relatively rotatable around the line in the Y axis direction and to be movable in a specific direction related to the positions of the feed tables; and displacement regulating means for regulating relative displacement of the feed tables in the guide tracks in the specific direction, the displacement regulating means being provided on the support/feed/turn output member, wherein the displacement regulating means comprises a hole and a piston, the piston being pushed out of the hole for pressing against the support/feed/turn output member to restrict the relative displacement in the specific direction.
