Description Universal, 3-jaw power chuck with outstanding sealing, long jaw stroke and integrated media feed-through. Field of application on universal CNC lathes on vertical turret lathes on mill/ turn machines on vertical pitch-up lathes Advantages – Your benefits Precision wedge hook power chuck for highest quality requirements Allows excellent machining processes High efficiency of the wedge hook system Process-reliable clamping due to high clamping forces Optimum jaw support for O.D. and I.D. clamping due to a very long base jaw guidance Allows high clamping forces at a long service life Optimized lubrication system Consistently high clamping forces are ensured Largest jaw stroke at high jaw clamping force Safe and variable clamping of workpieces over interfering contours Sealed against cooling lubricant and chips as standard via wiper strips, seals and sealed toolholder through bore Excellently suitable for the use on vertical lathes Media feed-through (coolant or air) as standard option integrated in the chuck body Flexibility depending on the application Low height Maximum use of the machine room and maximum rigidity of the system Base jaws with fine serration 1.5 mm x 60° and 1/16" x 90° as standard High flexibility in the range of top jaws All functional parts are ground and hardened Ensures a long service life Options and special information The wedge hook power chuck is excellently protected against dirt and chips. The technology of the ROTA NCO ensures highest precision and life time for applications on horizontal as well as vertical lathes. The long jaw stroke allows for clamping around interfering contours. Due to the media feed-through, the ROTA NCO chuck is a multi-purpose chuck. Central coolant supply, air feed-through or central lubrication are already standardized options and the chuck body is equipped for these modification possibilities.
