Options and special information

Sealed 6-jaw compensation chuck for deformation sensitive clamping of thin-walled workpieces
The SCHUNK ROTA NCR-A consists of a central chuck piston carrying three inner pendulums aligned at 120°. Each pendulum is connected to two base jaws. This ensures workpiece centering between six contact points, which can be adjusted in pairs. As the clamping forces are directed towards the chuck center, optimum centering is achieved without redundant dimensioning of the workpiece.
The special seals located on the serrated jaw interface and pistons of the SCHUNK ROTA NCR-A prevent grease from being flushed out and prevent the clamping force from being gradually lost. In addition, the seal prevents chips or dirt from ingress into the chuck body. This increases process reliability and lengthens maintenance intervals, translating into less frequent lubrication, and cleaning of the lathe chuck.
