Abstract: A multi-station, single action high precision mechanical vise for simultaneously clamping at least two work pieces with high dimensional stability and high holding forces. The multi-station work piece holder is used to hold a set of work pieces, so that sets of machining operations can be performed on the work pieces using the same tool, reducing the number of work tool change-outs needed when producing a large number of machined pieces.

Abstract: A combination tool mounted at a work station on the turret of a CNC lathe includes a cut-off tool having a tool holder body supporting a carbide cutter insert at its forward end. A bar puller mounted on the tool holder body has a pair of vertically spaced apart and forwardly extending spring fingers which carry opposing adjustable bar gripping jaws. The jaws receive and grip the free end portion of an associated bar therebetween upon further movement of the combination tool toward the bar after the cut-off tool has completed a cut-off operation on the bar.

Abstract: A bar puller mounted at a tool station on the turret of a numerically controlled turret lathe has opposing reversible, self-centering jaws biased toward each other and to a centered position for general alignment with the projecting end portion of a bar held by a rotary chuck mechanism, which comprises part of the lathe. The jaws receive and grip the projecting end portion of the bar therebetween when the bar puller is forced into engagement with the projecting end of the bar by movement of the turret. The bar puller may be adapted for mounting at either a boring or turning tool station on the turret. The jaws are adjustably positionable to receive and grip bars of differing size.
