Boring Fixtures

Boring fixture holds collet segments firmly in-place and puts collet under slight compression to ensure accuracy and roundness during machining.

The parameters shown represent a sampling of counter-bore possibilities. Other diameter/depth combinations are possible. Please contact Royal with your specific requirements.
For precise z-axis positioning, best practice is to use a Royal stop.
Users can counter-bore their own emergency collets, or order to size as hardened and ground specials.
For a better understanding of counter-bore collets and their use, please contact one of our applications engineers at 1-800-645-4174.
