Universal high-performance lathe chucks

Instead of exchanging lathe chucks and collet chucks, which can be tedious, just the top jaws of the ROTA NCD have to be exchanged against special collet jaws. This minimizes set-up times and allows a considerably higher output. The most striking feature of the ROTA NCD is its large through-hole, which allows machining of different bar diameters. Particularly for this type of application, SCHUNK has developed and patented collet jaws, which interlock at the front with the base jaws and therefore avoid a lift up of the chuck jaws. Since small bar diameters can also be precisely machined with lathe chucks, users save valuable time and high investments for additional special lathe chucks. Combined with common top jaws, many versions for I.D. and O.D. clamping can be designed, and users can choose between inch or metric serration. A continuous T-slot in the base jaws allow extreme positioning of the top jaws. In order to fulfill the increasing demand in quality, precision, and performance of turning operations, the lathe chuck is equipped with particularly long base jaw guidances, which optimally support the chuck jaws. The functional parts are hardened and ground on all sides, and also ensure continuous high run-out and repeat accuracy. High speeds can be achieved due to the wedge bar system for force transmission, and the low weight of the base jaws. Adidas
