FNC+ QUICK JAW CHANGE 3-JAW POWER CHUCK

Hardinge FNC260 Quick Change 3-jaw Power Chuck

The FNC+ 3-jaw power chuck is a universally applicable wedge style power chuck that offers a quick change jaw system as a standard feature. The jaws for the FNC+ are European Standard and the top tooling is easily interchangeable with other standard chuck models available in the industry. The patented trapezoidal wedge hook profile allows for the transfer of high gripping forces and optimum efficiency when machining at high speeds, while maintaining high accuracy. The jaw travel time for the FNC+ chucks is much quicker than most other quick change jaw chucks due to the shorter stroke of the central actuator. Designed to minimize weight, the FNC+ provides the option of running at higher speeds than most other quick change jaw style chucks.

The FNC+ has many available mounting adapters, ensuring capability with all common machine spindles. All Forkardt chucks are manufactured from the highest quality materials and are produced in accordance with the requirements of ISO 9001:2000.

The FNC+ is available as straight or angled serration version in sizes 185 – 630. For more information please contact our team at  (+1) 800 544-3823 or send an email request to tcsales@forkardt.com.
