Two station vise for manual or hydraulic operation with a quick-change stationary that can be carvable, hard or reversible. The stationary jaw having two precision through holes is placed on expanding pins, located on the top longitudinal rails of the vise body, that precisely position and tighten the stationary block in place. Two movable jaws connected by a tubular drive form an axially adjustable floating assembly. A manually turned tubular drive has an external threaded screw to move simultaneously the first jaw/nut and an internal thread that moves the second jaw/nut, on the opposite side of the stationary. Hydraulically parts are clamped at the two stations with a piston located in the second jaw/nut and connected axially with the first jaw/nut by the tubular drive. A setup-block located at the front jaw/nut keeps both jaws at proper position for loading and unloading of parts. The setup-block also allows for pre-clamping or retention of the part in the rear station before clamping.
