Options and special information

  • The design of the SCHUNK wedge bar power chuck ROTA NCD is based on the patented idea of high-precision clamping of the smallest workpiece diameters with SCHUNK collet jaws. At the same time it is possible to clamp large workpieces with all conventional top jaws. The continuous T-slot in the base jaws allows for the highest flexibility in positioning the top jaws.
