The innovative lathe chuck from the competence leader in clamping technology and gripping systems combines high clamping forces, maximum precision and minimum effort. In view of the continuously increasing quality requirements in modern metal cutting, the benefits of the Rota Ncs ensure a maximum investment safety. The company has done an excellent job during the development phases of power chucks. The achieved repeat accuracy achieves less than 0.01 mm and this is an outstanding lathe chuck for high-precision series production.
