Schunk unveils Rota NCX quick jaw change power chuck

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.
