O.D - Diameter ( See " Specification" for more info )

QUANTITY

Highest clamping forces even with largest jaw stroke

Universal, 3-jaw power chuck with outstanding sealing, long jaw stroke and integrated media feed-through.

Definition clamping force

The clamping force is the arithmetic sum of the individual forces occuring at the chuck jaws, distance “H“ at maximum pressure and maximum torque. The specifications exclusively refer to the grease used by SCHUNK.

Field of application

on universal CNC lathes
on vertical turret lathes
on mill/ turn machines

Precision wedge hook power chuck for highest quality requirements - Allows excellent machining processes
High efficiency of the wedge hook 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
Largest jaw stroke at high jaw clamping force - Safe and variable clamping of workpieces over interfering contours
Sealed against cooling lubricant and chips as standard via wiper strips, seals and sealed toolholder through bore - Excellently suitable for the use on vertical lathes
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
Base jaws with fine serration 1.5 mm x 60° and 1/16" x 90° as standard - High flexibility in the range of top jaws
All functional parts are ground and hardened - Ensures a long service life

The wedge hook power chuck is excellently protected against dirt and chips. The technology of the ROTA NCO ensures highest precision and life time for applications on horizontal as well as vertical lathes. The long jaw stroke allows for clamping around interfering contours.

Due to the media feed-through, the ROTA NCO chuck is a multi-purpose chuck. A central coolant or air feed-through is already prepared for in the chuck body as a standard option.
