1. Hydraulic cylinder-integrated mechanism, no hydraulic cylinder is needed.

2. Its accuracy is within 0.01mm, clamping accuracy is about 0.03～0.05mm(end face is 20mm)

3. The chuck is integrated, and has strong rigidity and high precision.

4. Strict dustproof to guarantee the bearing’s service life.

5. With strong grip to carry out heavy cutting.

6. Aluminum alloy cylinder body, light weight, great heat dissipation, and it can effectively reduce the temperature.

7. power source can be Air pressure or hydraulic pressure. This chuck can be used as Internal expansion and clamp workpiece.
