Options and special information

  • Hermetically sealed 6-jaw compensation chuck for series production
    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.
