ABSTRACT:
A tilting table for machining works is of the worm and worm wheel type incorporating a hydraulic servomechanism. A displacement of a stylus operating lever effected by the drive worm shaft moves the servocontrol valve out of its neutral position, thereby causing a tilting motion of the table in a desired direction via a hydraulic power unit of the mechanism. Due to a linkage connection between the table and the lever, the movement of the table always follows the lever so as to compensate the initial displacement, resulting in light and accurate positioning of the inclined table.
