5 Inch 6 Inch Standard High Precision 0.005 Hydraulic Three-jaw Chuck Claw Dresser Forming Ring Hydraulic Chuck Claw Boring Devi

The holding force is enhanced the accuracy of roundness and cylinder degree is improved and the trumpet centrifugal vibration will not be produced affecting the accuracy. Both the outer clip and the inner stretch can be used and the required size can be adjusted arbitrarily. The operation is quick and easy saving time and permanent use. After the old chuck is used into a circle the accuracy and holding force can be improved so that the recovery is the same as the new one. The use of forming problems not only can achieve the external clamping internal tensioning and through-forming three ways of forming but also can clamp the work object in the same state of forming so the core oscillation is less and the grasp force is improved. When using hard claw clamping the poor contact surface will produce a trumpet shape and the poor grasp force will produce centrifugal vibration affecting the accuracy and high risk.
