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.

This workholding solution satisfied the customer requirement in terms of quality and performance, and allowed them to achieve an elevated level of precision and productivity in their manufacturing operations.
