Power Chuck with added Clearance and less Weight

Description

SCHUNK introduces a new line of power chucks, the ROTA NCK-plus. In addition to features like a large through hole, an improved lubrication system, and high clamping repeatability, the ROTA NCK-plus is a direct replacement of nearly all OEM chucks. With tapered clearance designed into the chuck body, additional tooling clearance as well as increased spindle bearing life due to lighter weight can be realized.
The long precision piston guide and support guarantee less wear, a high level of continuous clamping accuracy, and long life. Combined with the industry’s best warranty of 2 years, this power chuck represents the best alternative as a replacement lathe chuck.
 
The jaw interfaces are 1.5 mm x 60° and 1/16 x 90° offering the user a high flexibility with regards to the use of existing top jaws.

The ROTA NCK-plus is available for all CNC lathes in the sizes 165 (6”), 210 (8”), 250 (10”), and 315 (12”), with clamping forces from 57 kN (12.814 lbf) to 144 kN (32.392 lbf). It is suitable for maximum speeds of 6,000 rpm and combines jaw strokes ranging from 2.75 (0.108”) – 5.30 mm (0.208”) per jaw.
