Compensation Chuck, 6-Jaw
Compensation Chuck, 6-Jaw
Schunk Intec India Pvt Ltd offers a 6-jaw Compensation Chuck, Rota NCR. The Rota NCR consists of a central chuck piston, which supports three pendulums, equally spaced every 120°. Every pendulum is connected with two base jaws. The result is a workpiece centering between six contact points, centered in pairs. The clamping forces are aligned with the chuck center. Therefore even raw parts can be centered without distortion of the workpiece. With its oscillating jaws, the chuck perfectly adjusts to the raw part. In case of conventional jaw clamping, this configuration allows maximum roundness of the workpieces, and also optimum centering. In case of finish machining, or clamping of pre-turned surfaces, the users can clamp the pendulum of the Rota NCR in centre position. In this configuration, a simultaneously centric motion of all six jaws takes place. If required, the 6-jaw chuck can be retrofitted with additional features: Bores for T-nuts or T-slot guidances for the clamping slide can be set. The chuck has clamping jaws that oscillate in pairs for concentric clamping. Two base jaws are always connected with a pendulum body. This assures workpiece centering between 6 contact points, which can be adjusted in pairs. Even pre-machined parts can be centered without distortion of the workpiece. For specific applications, the pendulum compensation can be blocked resulting in the centric clamping of the jaws.
