Description Hermetically sealed, 6-jaw power chuck with active jaw pull-down function. Field of application on universal CNC lathes on turn/mioll centers on vertical lathes Advantages – Your benefits Precision lever power chuck for top quality demands Allows excellent machining processes High efficiency of the lever system Process-reliable clamping due to high clamping forces Hermetically sealed Optimum protection against coolant and chips Permanently filled with oil Almost maintenance free with constant clamping force Active jaw pull-down No lifting of the workpiece from chuck face, highest requirements in face parallelism Media feed-through (coolant or air) as standard option integrated in the chuck body Flexibility depending on the application With integrated centrifugal force compensation Thereby high machining speeds are possible Easy change of base jaws Suitable for external and internal clamping Deformation sensitive clamping of thin-walled workpieces High degree of roundness of the workpieces Very accurate clamping of non-circular components Perfect for castings All functional parts are ground and hardened Ensures a long service life Options and special information The ROTA NCS is a hermetically sealed power lathe chuck with active pull-down action of the jaws. The chuck is suitable for external and internal clamping applications, the chuck size has to be selected for the corresponding workpiece size. The ROTA NCS is centrically clamping. At the 6-jaw chuck the pendulum mechanism is integrated. This assures workpiece centering between six contact points, which can be adjusted in pairs. Even pre-machined parts can be centered without distortion of the workpiece. The ROTA NCS is almost maintenance free, optimized for use in horizontal and vertical applications in high volume production.
