Model S Expanding Collet Assembly for Threaded Nose

Model-S Precision Expanding Collets

Precision internal chucking simplifies your tooling and machining operations. Precision results are assured when many operations are done in one chucking. The Model-S expanding collet assembly is precision engineered for small inside diameter chucking.

Concentricity requirements, like all machining specifications, are very rigid. With the Hardinge expanding collet unit, it is easy to obtain concentric and square shoulders, faces, and diameters with a previously machined bore. The Hardinge expanding collet adjusts to meet your most exacting requirements by means of four concentricity adjusting screws. Exact lengths are easily obtained since both the stationary expanding collet and work locating stop have no end movement. The work locating stop is machined in place during machine set up, assuring an absolutely square locating surface. When the collet is in the released position, it is smaller in diameter than the bore of the part. The result is fast and easy loading and unloading.
