Abstract: A dual vise is disclosed which has first and second vise assemblies. The vise assemblies have centrally fixed stationary jaws and independently controlled moveable jaws, each vise assembly being capable of holding a work piece under a pressure which is independent of the holding pressure for the other vise assembly, The pressure for each vise assembly is under the control of the operator. The moveable jaws are preferably controlled by concentric lead screw shafts. When used in conjunction with numerical control equipment, productivity is increased and damage to individual work pieces is reduced.
