ABSTRACT:
A vise for holding workpieces for precision machining which allows rapid set up, consistent workpiece orientation during machining and rapid cleanup. A stationary jaw providing a reference surface close to the operator, is removeably attached to a supporting structure. A moveable jaw is translated by a threaded shaft passing through the fixed jaw. Grooves of the supporting structure guide the movable jaw's translation. Axial clamping loads are transmitted from one jaw to the other directly by the threaded shaft rather than the support structure. The grooved supporting structure only provides resistance to moments tending to bend the shaft. The stationary jaw is readily removable allowing reversal, replacement or cleaning. Removal of the stationary jaw allows easy removal of threaded shaft and moveable jaw for replacement or cleaning without unthreading. Very high precision can be obtained by moment resisting design of the jaw assemblies.
