Collet pad top jaw systems from Dillon Manufacturing allow more varied geometries to be securely gripped, while also allowing more aggressive machining which shortens cycle times. With systems that can convert through-hole chucks to hold small bar and tube stock, and full contact of gripping surfaces to provide a more stable grip and allows heavier cuts, these Dillon products allow shops of all sizes to expand their capabilities.
Collet pads can be changed quickly, thus maximizing production time. Jaws can be adapted to many styles of chucks, making them ideal for special-purpose machining. Dillon collet pads and jaws are suitable for precision boring, high-speed machining, tapping, drilling and finishing. They are especially suited for small-diameter machining of stems, spools, crimp assemblies, manifolds for high pressure air systems, medical parts, miscellaneous fittings, mechanical and transmission components and specialty valves.
Metal-to-metal fits ensure accuracy; round, hex and square collet pad shapes with both smooth and serrated gripping surfaces available. 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.
Changing over to collet pad jaws is easily accomplished in just minutes with simply a jaw change, which is much faster and easier than changeover of entire chucks. The use of collet pad jaws allows users to maximize their chuck capabilities and more fully amortize their chuck investment by performing both chuck and collet pad projects.
Related Glossary Terms
Enlarging a hole that already has been drilled or cored. Generally, it is an operation of truing the previously drilled hole with a single-point, lathe-type tool. Boring is essentially internal turning, in that usually a single-point cutting tool forms the internal shape. Some tools are available with two cutting edges to balance cutting forces.
Workholding device that affixes to a mill, lathe or drill-press spindle. It holds a tool or workpiece by one end, allowing it to be rotated. May also be fitted to the machine table to hold a workpiece. Two or more adjustable jaws actually hold the tool or part. May be actuated manually, pneumatically, hydraulically or electrically. See collet.
Flexible-sided device that secures a tool or workpiece. Similar in function to a chuck, but can accommodate only a narrow size range. Typically provides greater gripping force and precision than a chuck. See chuck.
Machining operation in which a tap, with teeth on its periphery, cuts internal threads in a predrilled hole having a smaller diameter than the tap diameter. Threads are formed by a combined rotary and axial-relative motion between tap and workpiece. See tap.
Hole or cavity cut in a solid shape that connects with other holes or extends all the way through the workpiece.
