Sure-Grip Expanding Collet Systems - Collet-style & Spindle Mount

Product catalog summary

The Hardinge ID Gripping Advantage
Hardinge's Sure-Grip® Expanding Collet Systems are designed to tackle challenging machining tasks with precision and a wide gripping range. These systems are compatible with various machine brands and styles, including Collet-Style, Spindle-Mount Style, and Center Arbors, facilitating reduced changeover time and quick centering.

Collet-Style Systems
These systems, such as 5C, 16C, and 3J, mount directly into the spindle or collet adapter. They feature a solid, one-piece body and arbor combination, allowing for quick changeover between collet sizes. The systems ensure true parallel gripping and include a safety stop to prevent over-expansion.

Spindle-Mount Style Systems
Available in A2-5, A2-6, and A2-8, these systems mount directly onto the machine spindle without requiring centering adjustments. Changeover between arbor sizes is quick, taking approximately five to seven minutes.

Center Arbors for Precision Machining
Designed for grinding machines and lathes, these arbors can be held between centers or chucked on one end. They feature a precision locating shoulder and diameter for custom workpiece stops, maximizing productivity by allowing simultaneous loading and machining.

Wide Gripping Range
Sure-Grip Expanding Collets are available in 1/64" increments and metric sizes, with a range of +.015" to -.001" from the specified size, eliminating the need for decimal sizes.

Safety and Interchangeability
The systems include a built-in safety feature to prevent over-expansion and allow the use of interchangeable collets across different applications, enhancing versatility.

Dead-Length® Work Stops
These work stops ensure exact part length control by locating the part against the arbor face or a machineable work stop, resulting in stable parts with better surface finishes and closer tolerances.

Draw Bar Adapters
These adapters allow the Sure-Grip Expanding Collet System to be used on various spindles, including Hardinge and ANSI/ISO A2 series, with custom machining available for specific spindle requirements.

The Sure-Grip > Arbor assembly is designed to be used on grinding machines and lathes. The arbor can be held between centers, or chucked on one end and supported by a center on the other end. This expanding arbor assembly style is manually adjusted.The arbors have a precision locating shoulder and diameter so you can fabricate custom workpiece stops.Maximize your productivity by using two arbors. While one part is running, load the next part on the second arbor. Then you can load another arbor into the spindle when the first part is done. This is a big time saver when chucking one end of the...
