ABSTRACT:
A machine vice comprises an elasticity-adjustment rod secured to and penetrating one of two vertical portions of a subtantially U-shaped stress-transmission frame such that the one end of the frame is in contact with a vice head having a stationary jaw and a guide rail, whereby the flexing and strain of the stationary jaw resulting when a work is clamped between the stationary and movable jaws is compensated for, thus ensuring the perpendicularity of the stationary jaw with respect to the guide rail top surface and parallelness of the two jaws.
