Abstract

In construction of a metalworking vise having a fixed base, a stationary jaw mounted atop the front end portion of the fixed base, a slide jaw arranged facing the stationary jaw, and a piston movable into a hydraulic chamber to raise its fluid pressure, a holder shaft provided at its front end with an axial extension defining the hydraulic chambers and a force magnifying mechanism is arranged in the fixed base near the stationary jaw. The specified location of the force magnifying mechanism allow generation of a large clamp force at high precision in clamping position without causing any substantial warping of the fixed base.
