6-jaw power chuck without through-hole
6-jaw power chuck with oscillation mechanism for low-deformation clamping of thin-walled components. Also available with additional centrifugal force compensation system.

Advantages – Your benefits

  • Precision angle lever power chuck for top quality demands
    Allows excellent machining processes
  • High efficiency of the angle lever 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
  • 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
  • Optionally available with centrifugal force compensation
    Less clamping force loss at high RPM
  • Deformation sensitive clamping of thin-walled workpieces
    High degree of roundness of the workpieces
  • Very accurate clamping of non-circular components
    Perfect for castings
  • Turning ring simplifies and optimizes top jaw boring/machining
    Easy handling during boring/machining top jaws
  • All functional parts are ground and hardened
    Ensures a long life span

Options and special information

  • 6-jaw compensation chuck for deformation-sensitive clamping of thin-walled workpieces
    The 6-jaw compensation chuck is based on the principle of chuck jaws that oscillate in pairs. Two base jaws are always connected with a pendulum body. This ensures workpiece centering between six contact points, which can be adjusted in pairs. Even raw parts can be centered without distortion of the workpiece.
  • As a result, particularly deformation-sensitive workpieces, such as thin-walled rings, can be clamped with little deformation. The ROTA NCR chucks are still available in sizes Ø 165 mm and Ø 200 mm. With immediate effect, all larger sizes are covered by the sealed version ROTA NCR-A. Longer maintenance intervals are achieved due to the new sealing concept.
