Vulcanized Collet Systems

The new 80-mm FlexC vulcanized collet system features collet chucks mounted directly to the machine spindle. The collets are inserted and removed with a manual compression wrench for collet Vulcanized Collet Systemschangeover in less than 10 sec, which is eight times faster than it takes to change a collet in a standard collet chuck and 19 times faster than it takes to change three jaws on a jaw chuck. Quick changeover is not the only benefit of this system, which falls in the “special accuracy” collet classification having guaranteed accuracy within 0.0004” (.010-mm) TIR for style A (pull-back Dead-length stationary stop) and 0.0008” (0.020-mm) TIR for style DL (push-to-close). These systems achieve the same gripping capability as conventional collets while using less draw bar force. Additionally, the all too frequent variation in bar stock will no longer be a hindrance. The collet head has a gripping range of ±.020" (0.5 mm) of its nominal size to allow for variation in bar stock without having to change the collet.
