The clamping of thin-walled and easily deformed components is challenging. With its ROTA NCR 6-jaw compensation chuck, Schunk Inc. offers a standard solution for this type of workpiece. The company has now standardized the sizes of the ROTA NCR with diameters of up to 1,200mm 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 degrees. Each pendulum works in conjunction with three pairs of base jaws, resulting in six-point contact. With clamping force points being aligned towards the chuck center of rotation, even premachined parts can be centered without deformation of the workpiece. The ROTA NCR is available in sizes 165mm, 200mm, 250mm, 315mm, 400mm, 500mm, 630mm, 800mm, 1,000mm and 1,200mm diameters. The 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 1,200mm diameters.
