16C Dead Length Step Chuck with Ejector Assembly

With the Hardinge Dead-Length Collets and 2" Step Chucks, shoulders and faces can be machined to exact length, regardless of OD variations. Parts are loaded against an adjustable solid stop which is threaded into the inner collet. The inner collet is then spring loaded against the spindle face. There is no end movement. The low-cost inner collet and step chuck have a soft face and pilot hole to permit boring to size in the machine spindle for exacting concentricity. The inner collet is pinned to the outer collet to maintain location and original bored accuracy. The 5C Dead-Length Emergency Collet maximum depth of stop is: Under 7/8" round: 2-1/8" max. 7/8" to 1" inclusive: 1-3/8" max.
