Abstract: A workpiece holding system utilizing an improved vise having jaws that remain parallel with the workpiece and introduce a downward force on the workpiece to retain it against a precision supporting surface with the system of this invention primarily intended for use in holding workpieces on EDM wire machines. Each jaw has a step at the bottom which is significant when used on a wire EDM machine as it provides the ability to "pick up" the location of the workpiece from four sides. The system includes a dovetail incorporated into the vise with the position of the dovetail being the same regardless of the size of the vise thereby making it possible to use two different vises in a vertical setup to hold elongated workpieces accurately and making it easy to change from one vise to another.

Upon withdrawal of the pin from the hole, the brake automatically blocks backing plate rotation. By fixing the pin to the tool holder of a numerically-controlled machine tool, the latter is converted into a machine tool with an additional axis of movement, namely indexing rotation of the backing plate under the control of the tool holder.

Abstract: A device for supporting a workpiece 5 from a bench 4 in any required spatial position comprises two G-clamps 1 which are adjustably fixed to a metal tube 2 by clamping devices 3. Each of the devices 3 is operated by a single clamping screw having a handle 21 and when the clamping screw has been released, the device 3 can slide along, and turn about the axis of, the tube 2. Also, the clamp 1 can turn relative to the clamping device 3 about the axis of the clamping screw and about the axis of a pin 24 which is perpendicular to the axis of the clamping screw. This enables the workpiece 5 to be set in almost any desired position and orientation relative to the bench 4 and, when set, to be locked in its set position by tightening the two clamping screws by means of their handles 21. The device is therefore extremely versatile and it can, of course, alternatively be used to hold two workpieces in position relative to each other, for example while glued joints set.
