3 FNC Power chucks
Power operated chuck with quick change jaw system
in 3-jaw configuration
The FNC universally applicable power chucks belong to the most efficient and flexible chucks of the FORKARDT range of products. The unique advantage of this type is its quick change jaw system. The frequent change-over of jaws when processing small size batches continues with this chuck to be economical, due to minimum set-up times needed. Furthermore, sets of jaws that are already used with the proven manual chucks type F or F+ are 100 % compatible with FNC jaws. The patented wedge hook profile permits transfer of enormous gripping forces and optimum efficiency when machining at high speeds, especially where high accuracy is needed. Faster gripping on FNC chucks than on customary quick change jaw chucks is possible due to the shorter stroke of the central actuator for the same jaw movement. Many possibilities for mounting the FNC exist due to the modular design - thus ensuring compatibility to all common machine spindles. And of course, all FORKARDT chucks are manufactured from highest quality materials and are produced in accordance with the requirements of ISO 9001: 2000.

Technical Features:
? Optimum production efficiencies due to minimal jaw changeover times. ? Highest gripping forces and extreme accuracy. ? High grade, specially heat treated chuck body – one-piece, high strength and highly rigid construction – slim design with weight reducing cutouts. ? Mounting flanges for short taper mounting are available. ? FNC chucks may be equipped with standard jaws (hard or soft), claw jaws or special jaws.

Advantages at a glance:
? Reduction of jaw changeover time to a few seconds. ? Well proven F jaw system can also be used on FNC chucks, so many existing jaw sets can continue to be used. ? Closely maintained concentricity and repetitive accuracy as well as long service life ? Mounting accesories to suit any machine spindle. ? Extremely high gripping forces due to patented heavy duty, trapezoidal wedge hook actuation.

Chuck jaws
Power Chucks of the FNC series are delivered with the jaws of your choice:
Soft top jaws

FMB FWB

Soft jaws (type FMB / FWB) are used for the accurate clamping of already machined work pieces, on which clamping surfaces should not be damaged. These jaws are turned, by the user, under clamping pressure, to the respective clamping diameter to ensure extremely high accuracy and repeatability.

Roughing jaws

KBKTNC

For heavy duty machining of overhanging work pieces roughing jaws KBKTNC with replaceable chucking claws SKA (for external clamping) and SKI (for internal clamping) are available.

260.10.06 E 08/12

The chucking claws provide safest gripping even on short clamp surfaces.
