ROTA NCR
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.
Description
Advantages – Your benefits
- Precision angle lever power lathe 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.
