ABSTRACT:
To make parts requiring machining with the workpiece vise-held in different orientations, there is provided a precision vise having first and second pairs of jaws, each pair having a member which is fixedly located with respect to a reference location. The invention includes use of a particular form of vise for holding two pieces whereby the screw shaft that rotates to open or close the jaws is tensioned during tightening, which improves accuracy by avoiding bending stresses. When used in conjunction with suitable numerical-control equipment, the vise of the invention greatly increases productivity in the machining of product parts of the kind indicated above.
