It is a combination of the proven lathe chuck of the series ROTA-S plus and ROTA-S plus 2.0 with extended guideways, and transforms them into large, light chucks, which are particularly versatile in use. Compared to conventional lathe chucks used for large clamping diameters, the weight with ROTA-S flex drops down to 60%. At an identical table load much heavier workpieces can be machined, and due to the low height enough space remains for the workpiece and the tools. On the other hand, for machining smaller workpieces the extended guideways can be easily disassembled, so that the workpiece accessibility has been considerably improved compared to a clamping application with conventional large chucks. A special lubrication system ensures for permanently high clamping forces of both variants.
Dirt seals prevent chips and dust from entering the workpiece. 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 as reliably as large ones, and thereby ensures maximum operator’s safety. The clever clamping solution is available in the sizes 700, 1000, and 1200 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. The ROTA-S flex can be combined with numerous chuck jaws from the 1,200 types of the world’s largest standard chuck jaw program from SCHUNK.
