Dillon Soft Top Jaws Improve Concentricity, Chuck Balance

The soft jaws are designed to provide better concentric performance chuck balance, as well as enable a longer jaw life because of the increased jaw accuracy.

Dillon Manufacturing’s soft top jaws feature a milled surface on the jaw end of its soft jaw blanks, provides an easy-locating feature which speeds set-ups. In addition, this datum, opposite the clamping surface, serves as a location point for positioning the counter-bored holes and the jaws’ serrations resulting in exact dimensional matching of Dillon jaw sets. In addition to reducing set-up times, these features aid concentric performance, provide better chuck balance and enable a longer jaw life because of the increased jaw accuracy. As a result of having established surfaces in relation to the jaw serrations, Dillon says its chuck jaws consistently perform as a standard workholding component for turned or bored parts.

The jaws are available in 1018 steel and 6061 aluminum, as well as 4140, 8620 and A2, brass, delrin or stainless steel to suit most CNC or manual chuck projects involving turned or bored parts. They are said to be ideal for second operation finishing work such as shafts, gear blanks, wheel hub and bearings, and more.
