Turning chuck KNCS-2G series

for aeronautics

The most fl exible production chuck in the world QUICK JAW CHANGE FULLY SEALED Quick jaw change power chucks Large through hole Protection against dust and swarf High flexibility: jaws radially adjustable/reversible 3 Jaws Evolution of the quick jaw change power chuck KNCS-N. The KNCS-2G features additional seals and an improved lubrication system for low maintenance. The chuck still offers all the advantages same as the KNCS-N. The proven wedge bar drive guarantees unmatched accuracy and rigidity. A low loss of grip force due to centrifugal force makes the chuck ideal for high speed applications. This design does not require any counterbalance weights which allows highest speeds without vibration. Sealing: The KNCS-2G is sealed by seals attached to both faces of the base jaws. Also the wedge bars are protected by mechanical seals. The seals protect the chuck against penetration of dirt and swarf. Low Maintenance: The lubrication system of the KNCS-2G is optimized. Additional lubrication channels and grease pockets integrated in the jaw guide ways ensure constant clamping force. The lubrication intervals are signifi cantly longer reducing down times and cost for maintenance. Mass production: The sealing and the new lubrication system make the KNCS-2G also suitable for mass production. Compatibility: The KNCS-2G is interchangeable with the standard series of quick jaw change chucks KNCS-N. Existing master jaws still can be used without sealing. A small modification made to the master jaws and a mounting kit can upgrade existing master jaws to become 2G master jaws.
