The ROTA THW3 flexible-jaw quick-change chuck from Schunk manages a balancing act between short set-up times and low maintenance. Its overall package of functional design, flexibility and sustainability also convinced the jury of the iF Design Award 2022.

Idea, form and function – these were just some of the criteria used by the design experts to determine this year’s winners of the iF Design Award. Aesthetically, the ROTA THW3 jaw quick-change chuck achieved high marks with its optimised outer geometry and fewer interfering edges. However, it was the chuck’s function that impressed on multiple levels. Schunk has cut down on weight in the product design, which helps to reduce energy input and enables faster acceleration and braking behaviour of the lathe. Nevertheless, the lathe chuck still has a highly rigid base body that ensures process-reliable clamping, even under maximum stress. Equipped with a quick-change jaw system, the ROTA THW3 can be quickly converted for a new range of parts and has a jaw repeat accuracy of <0.02 mm. In addition to its functionality, the jury was also impressed by the sustainable focus of the clamping device. Patented sealing has allowed cleaning and maintenance intervals to be up to 20 times longer than with comparable products, reducing the use of lubricants, cleaning agents and water, and helping to protect the environment. By using resources sparingly, it makes a successful contribution to sustainable production while ensuring optimal functionality. For further information www.schunk.com
