Original Press Release:

Maximize Flexibility on Mill/Turn Machines with The New SCHUNK ROTA-M Flex 2+2

SCHUNK has developed the ROTA-M flex 2+2, a low-maintenance 2+2 chuck jaw specially designed for meeting the increasing demands of the market. The patent-pending compensating mechanism provides a very long compensation stroke: Depending on the size, it amounts to 5.1 mm up to 10 mm per jaw – more than other available 4-jaw chucks on the market. This means increased flexibility for clampable workpiece geometries and a wide variety of possible applications. In many cases a single ROTA-M flex 2+2 chuck will be sufficient for covering a wide range of part geometries.

Sealed guideways

Special seals on the guideways prevent grease from washing out under coolant pressure and gradual loss of clamping force. Even in case of low clamping forces, precise functioning of the chuck is ensured. At the same time, the sealings protect the chuck body against chips and dirt, process safety increases and maintenance intervals are extended. For increased safety, the SCHUNK ROTA-M flex 2+2 clamping is done in a self-locking manner, and the clamping condition is signaled via indicating pins. The standard chuck sizes 260 to 1200 achieve jaw strokes from 9.5 mm to 17.8 mm and high clamping forces from 100 kN to 180 kN.

Serial extras for large chuck sizes

As of size 800, users benefit from the weight-reduced design. The chuck face is equipped with grooves, and fixed stops allow the chuck to also be used as a vise. Moreover, the large sizes are designed for use on vertical lathes. The SCHUNK ROTA-M flex 2+2 is equipped with a flexible serration (1.5 mm x 60° or 1/16“x 90°) so that the user can fully exploit the benefits of the world’s largest range of standard chuck jaws from SCHUNK.
