Schunk has developed the highly flexible manual chuck ROTA-S flex particularly for machining a wide workpiece range on mill-turn machines. It is the lathe chuck ROTA-S plus with extended guideways transformed into a large, lightweight chuck (for its capacity), which makes it versatile, the company says.

Compared with conventional lathe chucks used for large clamping diameters, the weight with ROTA-S flex is approximately 60 percent of a conventional chuck with the same capacity. At an identical table load, much heavier workpieces can be machined, and because of the low height, enough space remains for the workpiece and the tools. For machining small workpieces, the extended guideways can easily be disassembled, considerably improving workpiece accessibility compared with a clamping application with conventional large chucks. A special lubrication system ensures permanently high clamping forces for both versions. Dirt seals prevent chips and dust from entering the chuck.

The ROTA-S flex can be easily assembled on a machine table, and by using the optimized jaw quick-change system, retrofitting can be done within seconds. The chuck clamps small parts and large ones. The clamping solution is available in sizes 700, 1,000, and 1,200 for ROTA-S plus, and the manual chuck ROTA-S plus 2.0 is available in sizes 315, 400 and 500. Depending on the size, the chuck (without top jaws) weighs 170 kg, 360 kg or 490 kg respectively. The ROTA-S flex can be combined with numerous chuck jaws.
