Precision internal chucking will simplify your tooling and machining operations. Precision results are assured when many operations are done in one 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 the machine set up assuring an absolutely square locating surface. When the expanding collet is in the released position it is smaller in diameter than the bore of the part. This makes for fast easy loading and unloading of work. Turned Range of the Series S Collets are .562 inch to .750 inch.
