When the chuck is engaged, the jaws move inward towards the center of the chuck, gripping the workpiece securely.   The floating claw design ensures that the clamping force is evenly distributed on the workpiece, minimizing the risk of deformation or damage.


Floating claw power chucks are often used in precision machining applications where high accuracy and repeatability are required. They are commonly utilized in turning, milling, and grinding operations for holding cylindrical or irregularly shaped workpieces.




Technical features

Clamping direction bears horizontal pushing force, the same as the clamping way of ordinary power chuck

Tooth form basic claw, convenient for adjustment

Compensation clamping with radial displacement function of the claw

Centrifugal force compensation to overcome the high speed rotating

Replaceable telescopic tip, with fine-tuning function of radial accuracy
