超长，对称的导向槽，非常适合外卡或内卡，卡盘体和内部零件经过表面淬火和麿削处理，大大提高了刚性，耐用度和精度;由于楔块机构被沿切线方向支撑，即使在高速时夹紧力损失也非常低，主轴快速停止后，夹紧力增加（滞后）非常小。 
| Clamping glossary | | | Case hardening: The surface of the components
is hardened (60 HRC) 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.Hysteresis: At high speeds the chuck body "grows" due to centrifugal force. The draw pull 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. SMW-AUTOBLOK chucks with wedge bar drive
have a very long hysteresis. 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. Inch serration: The connection inbetween top jaws and master jaws is done through serration, T-nuts and bolts ording to DIN 6353 (serration 90°, pitch in inches). This ist standard on European chucks. HFKN chucks can be supplied either with inch serration or metric serration. Metric serration:The connection inbetween top jaws and master jaws is done through serration,
T-nuts and bolts ording to ISO 9401 (serration 60°", pitch in mm). This is standard on Japanese chucks. Efficiency: Efficiency is the ratio between the calculated theoretical gripping force (disregarding friction) and the actual (measured) gripping force. |
