1. It is composed of a variety of rotary cylinders with different cylinder diameters, which can meet the requirements of different clamping forces at the same time, when the workpiece has a variety of thicknesses.
2. The overall compact structure is suitable for the use of narrow space.
3. The tolerance of flatness and parallelism of the upper and lower mounting surfaces is below 0.005mm,and wear resistant materials are used on the mounting surfaces to ensure the machining accuracy of the products.
4. The magnetic ring design facilitates automatic control.
