ROTA NCR Precision 6-Jaw Compensation Chuck

The clamping of thin-walled and easily deformed components is challenging. With its ROTA NCR 6-jaw compensation chuck, SCHUNK offers a standard solution for this type of workpiece. SCHUNK has now standardized the sizes of the ROTA NCR with diameters of up to 1200 mm and, in doing so, opened up the possibilities for precision workpiece clamping with large lathe chucks. 

The ROTA NCR consists of a central chuck piston, which has three inner pendulums positioned at 120°. Each pendulum works in conjunction with three pairs of base jaws, resulting in 6-point contact. With clamping force points being aligned towards the chuck center of rotation, even pre-machined parts can be centered without deformation of the workpiece. The ROTA NCR is available in sizes 165, 200, 250, 315, 400, 500, 630, 800, 1000 and 1200 mm diameters.

SCHUNK’s ROTA NCR chuck offering can also be utilized on virtually any turning application. For example, the challenge of contamination issues caused by the machining of materials like gray cast iron can be minimized by the utilization of SCHUNK’s vertical turning product, also available in sizes up to 1200 mm diameters.
