  • Patent number: 4925168
    Abstract: A vise for clamping a workpiece in an adjusted position during operation on the workpiece by a tool, particularly the cutting wire of an electric wire cut discharge machine. For maintaining accuracy of the clamped workpiece and still occupying a minimum of space by the vise within the working range of the machine tool the vise is provided with a first fixed jaw and a second jaw movable along ways forming a reference surface. Wedging abutment surfaces and abutting surfaces are formed on the bed of the vise and on the second jaw, respectively, which engage during clamping the workpiece for preventing bending of the ways which allows a low profile construction of the vise.
