The original quick jaw change power chuck. High repeatability when changing jaws

Transcription

1 Fast changeover, fast payback: The original quick jaw change power chuck KNCS N Easy lubrication even on vertical machines with 3 radial builtin grease fittings Minimal setup times Jaw change in less than 1 minute igh repeatability when changing jaws Extra long, symmetrical jaw guides. Ideal for O.D. or I.D. clamping No reboring of already machined jaws necessary, because runout < 0.02 mm ( 210) Flexibility jaws can be radially adjusted and are reversible = less jaw sets Direct mounting Jaws radially adjustable Recess and bolt circle to DIN Jaws 1 reversed Profitability Vertical application Example setup times/costs Jaw change Reboring of jaws Ø jaw changes/day Working days/year Machine costs/hour Total costs/year Profit* Conventional chuck 10 Min. 20 Min $. $ KNCS N 1 Min. 0 Min $. $ 4. $ * If jaws are changed more often, the profitability is increased accordingly. SMWAUTOOK Version for vertical application with cover and drain holes for coolant available. Unique wedge bar drive for high speed. Minimum loss in gripping force because of tangentially supported wedge bars. Minimum increase of gripping force (hysteresis) after quick spindle stop. igh efficiency of the wedge bar drive ensures highest concentricity and repeatability. Suitable for highlow clamping Original SMWAUTOOK quick jaw change. Jaw change accuracy with patented jaw safety interlock Serration is not fully engaged jaw safety interlock active.

2 Clamping glossary Case hardening: The surface of the components is hardened ( RC) to a depth of about 1 mm (0.04 ). The core shows a high tensile strength and toughness. Compared to partial inductive hardened and nitrited parts the rigidity and the resistance against wear is greatly increased. Efficiency: The ratio between the calculated theoretical gripping force (disregarding friction) and the actual (measured) gripping force. ighlow clamping: For easily deformed components. igh gripping forces for the rough cut are reduced to low gripping forces for the finish cut without unchucking. This means less deformation on the finished components. Contrarily to wedge hook chucks the wedge bar drive is suitable for highlow clamping. ysteresis: At high speeds the chuck body grows due to centrifugal force. The drawpull of the clamping cylinder causes an increase in gripping force which cannot be decreased at a quick spindle stop (or change in speed). This can cause deformation at easily deformed parts. chucks with wedge bar drive have a very low hysteresis. Jaw change accuracy: The centering accuracy after a jaw change with once already bored/ground jaws on the chuck. The clamping force on the is transmitted via the wedge bar drive. selfacting cleaning of the serration offers a constant high jaw change accuracy after jaw changing. Jaw safety interlock: At quick jaw change chucks the transmission of the gripping force to the interchangeable clamping jaws is done via a serration. With existing chuck designs misoperation by the operator can cause danger to man and machine if the jaw is not inserted correctly i.e. the serration is not fully engaged. The is equipped with a unique safety interlock: The builtin safety interlock eliminates misoperation. Repeatability: The centering accuracy of the chuck equipped with one set of jaws starting from the first up to the last component of a batch. Due to the wedge bar drive chucks offer a much higherrepeatability compared to wedge hook chucks. Wedge bar drive: The chuck is driven by tangentially mounted wedge bars. This design allows highest repeatability and rigidity. These chucks have very low loss in gripping force due to centrifugal force. The design does not require counterbalance weights which allows highest speeds without vibration. The engaging/disengaging of the jaws is done by an additional tangential movement of the wedge bars. This proven and patented design with Chuck body and internal parts are case hardened and ground. For highest rigidity, durability and precision arge through hole for full use of spindle bore SMWAUTOOK 111 3
