ABSTRACT:
The disclosure relates to a torque limiting vise for holding work on a machine tool table. The vise has a pair of relatively adjustable jaws between which parts may be clamped and held on a machine tool table and one of the jaws of the vise is advanced toward the other one by means of screwthreaded means having torque limiting means adapted to limit the torque of the screwthreaded means to a predetermined amount so as to limit the clamping force between the jaws to a predetermined amount, and thereby to limit mechanical deflection of the jaws to a predetermined amount so that each time a part is clamped between the jaws, the amount of deflection of the jaws is repeated and thereby permitting repeated machining operations with precisely the same holding position of the part between the jaws as it may relate to a cutting tool spindle axis of the machine tool upon which the vise is used.
