Quick-change chuck for lathes with short stroke cylinder

Jaw quick-change chucks from SCHUNK, the competence leader for clamping technology and gripping systems particularly pay off very quickly for turning smaller and medium-sized series. After the success of the SCHUNK ROTA THW plus wedge bar power chucks, SCHUNK, the family-owned company transfers the principle of the fast jaw change to CNC lathes with short stroke cylinders.

The universal SCHUNK ROTA NCX power chuck can replace conventional lathe chucks without jaw quick-change system 1:1 without any conversion on the machine. It minimizes the effort for set-up, and extends the productive machine running times. 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 metal cutting. For ensuring maximum operational safety, it is equipped with a jaw locking system, and a jaw presence monitoring. Due to the individual base jaw system, it is particularly interesting for users who do not yet work with a jaw quick-change chuck. Every type of standard top jaws with tongue and groove can be used as top jaws.

The universal SCHUNK ROTA NCX chuck will be available at of beginning of 2015 in the sizes 165, 215, 260, and 315 with a through-hole of diameter 53 to 106 mm, a jaw stroke from 3 to 6.3 mm, and a clamping force from 55 to 155 kN. It can be used for I.D. and O.D. clamping.
