Concentric clamping.

The constant challenge in metalworking is clamping thin-walled workpieces that can easily deform. Schunk Inc. has introduced a new six-jaw power chuck, ROTA NCR, developed specifically to avoid distorting delicate material. With six-point contact on the workpiece, even pre-machined parts can be clamped without any deformation.

[ILLUSTRATION OMITTED]

The ROTA NCR consists of a central chuck piston that has master jaws oscillating in pairs for concentric clamping. A pendulum is connected to each set of two base jaws. The result is that the workpiece is centered between six points of contact in which the members of each pair lie opposite one another. Schunk Inc., www.rsleads.com/805tp-210
