Lightweight design - Lathe chucks available in three versions
28.09.2011 -
Shorter cycle times, lower energy consumption, less wear - weight-reduced lathe chucks offer an entire package of benefits. The key is knowing the best one to pick from the technogical and economic point of view? With the ROTA NCL lightweight lathe chuck, SCHUNK, the competence leader for clamping technology and gripping systems wants to find the answer on this question. The powerful lightweight is available in three versions: As a weight-optimized steel-, a light aluminum-, and in an ultra-light carbon version.
Compared with conventional power chucks, the weight of the ROTA NCL in steel version is reduced by 35%, in aluminum by 54%, and in carbon by 62%. Whereas the weight-reduced steel chuck is already in series production, the other two versions are still being studied. Extensive tests will attempt to prove whether lighter chucks really are better. Because of this, technological and economic aspects are important for the innovative family-owned company "What is the use of an extremely light chuck, if it is too expensive for consumers to buy?" Markus Michelberger, Head of Sales Workholding Systems asks. Is the light-weight steel chuck perhaps the more economic, and therefore particularly promising solution? It has been proven that the weight reduction of more than one third allows the lathe chuck to be quickly accelerated and slowed down, which particularly pays off in automated mass production.
From the construction point of view, all three variants have the same design. The patent pending double cylinder version of the base jaws ensures that the forces are optimally distributed on the chuck body. With its large through hole, the low-maintenance, completely sealed, and permanently lubricated chucks are ideal for the use in modern lathes. For fully maintaining clamping force, rigidity, and precision, every component which is in the direct flux of force are made of extremely resistant hardened steel. The chuck bodies themselves are completely made of steel, aluminum or CFK. Endurance tests show, how the lightweight chucks behave in the lathe, and that clamping forces and repeat accuracies can be permanently ensured. Even the crash behavior, and the manufacturing process require detailed investigation. SCHUNK expects the first results in the course of the next year. Those who want to profit from the advantages of a lightweight lathe chuck, can purchase the weight-reduced ROTA NCL steel version, where the price- and energy effects have an optimal ratio.
