Abstract

A vise adapted to clamp a workpiece includes a support which has a slide surface, first and second jaws movable with respect to one another, and operable to clamp the workpiece, and wherein at least one jaw is slidable along the slide surface. A drive element is in driving connection with at least one jaw so as to at least move that jaw into engagement with the workpiece, and a drive mechanism is operable to drive the drive element. A stressing mechanism is provided for pressing the jaw against the slide surface upon the drive element driving the jaw into engagement with the workpiece.
