1.Dealt by the Forming Ring ,can improve the precision and clamp capacity of the used collets ,just like new collets .
2.There are three kind usage of forming ring ,clamp expand and punch-through molding ,and can process the collets in the same way ,minimize the vibration ,enhance the grasp force .Process collets by using forming ring ,grasp force can reach 100%,and improve the precision.When use hard claw ,if the surface doesn't touch well,will from Bell-shape,and develop centrifugal Vibration due to the poor grasp force ,then influence the accuracy and increase the risk.
