FlexC Vulcanized Collet Systems

Hardinge FlexC Collet Systems are flexible, sealed collet heads that interchange in seconds and are available with spindle mounts for all brands of CNC lathes.

Thru-hole, pull-back stationary stop and push-to-close dead-length styles are available for main and sub-spindle CNC lathe applications.

Hardinge guarantees accuracy within 0.0004" TIR for the collet system models A and D, and 0.0008" TIR for style DL.

The changeover concept is simple using a manual wrench to compress the collet for quick removal or replacement in seconds.

A typical FlexC collet head has a gripping range of 0.020" (0.5mm) above and below its nominal size to allow variation in bar stock without having to change the collet.

There is no collet shank, so the collet segments remain parallel to the stock even when there are variations in the stock size. Parallel clamping minimizes stock "push back" and requires less draw bar force as compared to conventional collets.

Hardinge has invested in the latest vulcanizing machines made by DESMA. The vulcanization process joins the collet segments together as a one-piece unit with a permanent bond. Vulcanized rubber has elasticity for repeated opening and closing over the life of the collet. Because of the sealed design, it prevents chips from entering the collet system.

An emergency collet can be kept on hand for just-in-time machining when the proper size hardened collet is not immediately available.
