This document provides specifications and instructions for a forming device that allows for faster, easier, and more accurate machining of soft jaws for chucks. The forming device attaches in seconds without tools, fits a range of chuck sizes from 6 to 13 inches, and machines the jaws at the same clamping pressure used to hold workpieces, improving accuracy. It reduces setup time and minimizes stock removal to make soft jaws last longer, providing a cost-effective solution.
