Collet Pad Top Jaws Expand Chuck Workholding Capabilities

Collet pad top jaws from Dillon Manufacturing is said to enable aggressive machining to reduce cycle times and provide consistent repeatability. Full contact of gripping surfaces provides a stable grip and allows heavier cuts, while metal-to-metal fits ensure accuracy, says the company.

Round, hex and square collet pad shapes are available with smooth and serrated gripping surfaces. The line includes collet pad top jaws and W&S solid emergency collet pads, as well as S-type, Gisholt, Jones & Lamson, and Martin collet pad types. Dillon collet pad jaws are said to increase a given chuck’s range of workholding capabilities.

The jaws can convert through-hole chucks to hold small bar and tube stock. According to the company, the jaws can be changed quickly—often in a few minutes—whereas changing the entire chuck may require several hours of labor.

Dillon collet pads and jaws are designed for small-diameter machining of stems, spools, crimp assemblies, manifolds for high-pressure air systems, medical parts, miscellaneous fittings, mechanical and transmission components, specialty valves, and more.
