ABSTRACT:
The invention is an improvement to machining vises that allows the effective width between the opposing jaw faces to be variably increased beyond that of the standard opposing faces of the stationary and movable jaws. To provide the increased jaw width, jaw segments having a notched reception area are received in key-ways extending laterally across extended upper surfaces of the stationary and movable jaws. At least one key-way is formed on the upper surface of the stationary jaw and at least two key-ways are formed in the upper surface of the movable jaw. The number and placement of the jaw segments are determined by the configuration of the workpiece to be machined so as to properly hold the workpiece in such a manner the machining operation is not obstructed.
