Forkardt, a Hardinge brand and international provider of work-holding solutions and accessories, has upgraded its FNC+ quick jaw change power chuck, a universally applicable wedge style power chuck offering increased versatility and manufacturing efficiencies, as well as reduced set up time.
New features and capabilities include a revised base jaw profile that allows the chuck to accept base jaws from competitive brands. This capability permits users to continue utilising the current inventory of base jaws, irrespective of manufacturer. In addition, the through-hole is now larger to meet the needs of today’s machine tool builders and dealers.
The chuck also features a more compact design, where the FNC+’s reduced chuck body weight results in less mass on the spindle, allowing machine manufacturers to permit/machine a higher workpiece weight and attain higher spindle speeds than ever before. Furthermore, the low overall height allows customers to machine longer parts, simultaneously increasing the usable work envelope of the machine.
Another upgrade is the newly designed and installed piston safety device, which makes it possible to easily and safely mount FNC+ on vertical spindles, while the clamping chuck jaws can now only be unlocked, adjusted and changed with the original actuating key.
Forkardt’s FNC+ also 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 to 630.
