Custom Chuck Jaws – Michigan

Our many customers in the automotive industry know that when a complicated custom workholding solution is needed, Toolcraft, LLC will provide a quality tool, competitively priced, delivered in a timely fashion.

We turned and milled the custom chuck jaws highlighted here from cold rolled steel. To create the unique geometry of the jaw, our machinists developed a positional workholding strategy of using a shaping fixture mounted to our 4-jaw chuck to guide the cutting tools. Through this process, we were able to machine each of the three jaws, which featured dimensions of 1 ¾” in length x 2 ¼” in width x 5 ¼” in height, to within tight +/-.0005″ tolerances. Case hardened 1/32″ deep to RC40-45 to promote a long tool life; we shipped them to the customer within a 4 week turnaround.
