• 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.
