ROTA NCR Precision 6-Jaw Compensation Chuck

"The clamping of thin-walled and easily deformed components can be difficult. SCHUNK offers the 6-jaw ROTA NCR for this challenging clamping scenario with standard chuck diameters ranging from O 165 to O 1,200 mm, for large workpieces," said a company spokesperson.

The 6-jaw NCR chuck's strengths lie in its 3 pairs of radially compensating jaws that more equally distribute the chuck clamp force about the circumference of the workpiece, with 6 points of contact, as opposed to the conventional 3-point clamping profile found with 3-jaw chucks.

"Suitable for thin-walled or deformation sensitive parts, even rough castings or rings can be centered with minimal distortion to the workpiece," said the spokesperson. The NCR can easily be switched from compensating to centric clamping mode by simply tightening a bolt under the center cover plate of the chuck.

The NCR also can be outfitted with optional centrifugal force compensation and has provisions for coolant and air media pass-through. In addition, as standard features, the NCR includes optimized internal greasing system, hardened chuck body, hardened and ground internals. The NCR is available in sizes O165, 200, 250, 315, 400, 500, 630, 800, 1,000 and 1,200 mm with serrated or metric tongue and groove base jaw interfaces.
