Schunk is transferring the principle of fast jaw changes to CNC lathes that have short stroke cylinders. Its universal Schunk Rota NCX power chuck can replace conventional lathe chucks without a quick jaw change system, and without any conversion on the machine (or any need for an adapter).
The system minimises the effort required for set-up by up to 80%, says Schunk. Within 60 seconds, a new jaw set is retrofitted with a repeat accuracy of 0.02 mm.
The Rota NCX is suitable for finishing and volume metalcutting. For ensuring maximum operational safety, it is equipped with a jaw locking system and jaw presence monitoring.
The chuck is available in the sizes 165, 215, 260, and 315, with a through-hole diameter of 53 to 106 mm and a clamping force from 55 to 155 kN. It can be used for both ID and OD clamping.
