ABSTRACT:
A rotary table for holding a workpiece for machining. The rotary table comprises a base, a rotary member supported by the base, a transversely movable member carried by the rotary member, a laterally movable member carried by the transversely movable member, a lead screw device for displacing the laterally movable and transversely movable members, and a worm and worm gear for selectively rotating the rotary member relative to the base. The rotary table includes a thrust bearing for supporting the rotary member against the base, and a biasing means abutting the thrust bearing at one end and abutting the rotary member at another end to allow a slight contact between the rotary member and the base to exclude dirt and allow rotation of the rotary member relative to the base with a minimum amount of friction.
