ABSTRACT:
A screw-nut feed mechanism for effecting displacement of a movable table on a guiding base or bed in accordance with rotation of a feed screw shaft mounted on the guiding base. Ther feed mechanism includes a ball nut assembly threadedly coupled with the feed screw shaft, and a floatably supporting member for floatably supporting the ball nut assembly. The floatably supporting member is composed of a board having a predetermined thickness in a direction parallel to the rotational axis of the feed screw shaft. The floatably supporting member is formed with plural slots penetrating the floatably supporting member in a direction parallel to the axis of the feed screw shaft so as to form a fixed portion, a first floating portion, first flexible connecting portions which support the first floating portion for movement relative to the fixed portion in a first direction perpendicular to the axis of the feed screw shaft, a second floating portion, and second flexible connecting portions which support the second floating portion for movement relative to the first floating portion in a second direction perpendicular to the axis of the feed screw shaft and the first axis. The ball nut assembly is secured to the second floating portion of the floatably supporting member.
