Description Universal, wedge-bar-based, 3-jaw power chuck with continuous T-slot in the base jaws for maximum jaw adjustment range. Available as 2-jaw chuck on request. Field of application on universal CNC lathes on turn/mioll centers on vertical pick-up lathes Advantages – Your benefits Large through-hole Machining of all standard pipe diameters High efficiency of the wedge bar system Process-reliable clamping due to high clamping forces Optimum jaw support for O.D. and I.D. clamping due to a very long base jaw guidance Allows high clamping forces at a long service life Extremely rigid clamping High precision on the workpiece Clamping of smallest diameters possible Flexibility for various clamping tasks Base jaws with fine serration 1.5 mm x 60° and 1/16" x 90° as standard High flexibility in the range of top jaws Two mounting bolt circles For fast and direct attachment to all commercially available spindle heads All functional parts are ground and hardened Ensures a long service life 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.
