The clamping of thin-walled and easily deformed components can be difficult. SCHUNK (Morrisville, NC) offers the 6-jaw ROTA NCR from its lineup for this challenging clamping scenario, with standard chuck diameters ranging all the way from Ø165 to Ø1200mm, for large workpieces. According to the company, the 6-jaw NCR chuck’s strengths lie in its 3 pairs of radially compensating jaws which 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.
Perfect for thin-walled or deformation sensitive parts, even rough castings or rings can be centered with minimal distortion to the workpiece. The NCR can also easily be switch from compensating to centric clamping mode by simply tightening a bolt under the center cover plate of the chuck.
