Forkhardt’s FNC+ Quick Jaw Change Power Chuck Offers Manufacturing Versatility

Forkardt’s FNC+ Quick Jaw Change Power Chuck is a universally applicable, wedge-style power chuck offering increased versatility and manufacturing efficiencies as well as reduced setup time. New features and capabilities include a revised base jaw profile that enables the chuck to accept base jaws from competitive brands. This enables users to continue to utilize the current inventory of base jaws, irrespective of brand. In addition, the through-hole has been enlarged.

The chuck also has a more compact design. FNC+’s reduced chuck body weight results in having less mass on the spindle and enables machine manufacturers to permit/machine a higher workpiece weight and attain higher rpms. The low overall height enables customers to machine longer parts and increases the usable work envelope of the machine.

With the newly designed and installed piston safety device, FNC+ can be easily and safely mounted on vertical spindles and the clamping chuck jaws can now only be unlocked, adjusted and changed with the original actuating key, the company says. The standard model comes with an angled or straight tooth base jaw, while the straight tooth model will accept competitive brands’ base jaw. The chuck now mounts with six instead of three bolts to the spindle, offering a higher rigidity of the chuck body. The 3FNC+ is available as straight or angled serration version in sizes 185-630.
