Germany – Schunk has launched the Rota NCX quick-change chuck for lathes with short-stroke cylinders.
According to Schunk, the NCX can replace conventional lathe chucks without a quick-change jaw system on a 1:1 basis without any conversions on the machine. This is said to minimise set-up time, while extending machine running times. A new jaw set can be retrofitted with an accuracy of 0.02 mm within 60 seconds, the supplier says and adds that the NCX is suitable for finish-machining as well as high-volume production.
To ensure operational safety the NCX is equipped with a jaw locking system and jaw presence monitoring. With an individual base jaw system, the Rota NCX becomes particularly appealing for users that do not yet work with a quick-change jaw chuck. Moreover, all standard top jaws with tongue and grooves can be used as top jaws, Schunk says. The NCX is available in sizes 165, 215, 260, and 315 mm with a through-hole diameter measuring 53 mm to 106 mm, a jaw stroke of 3 to 6.3 mm, and a clamping force of 55 to 155 kN. The unit can also be used for I.D. and O.D. clamping.
