2.Spring Collet 46-50HRC;
3. Precision Collet Two kinds of appearance can be provided: polishing or coating treatment;
4. Straight Shank Collet,The inner hole, the outer circle and the end face are grinded many times, reaching Ra0.4, which has a mirror effect.
5. Surface "environmental protection" special coating treatment, improve surface hardness, wear resistance, improve cleanliness, more stable accuracy, smoother surface, better anti-rust, anti-corrosion effect, feel more comfortable, appearance more beautiful.
Cryogenic treatment
6.  Straight Spring Collet Ultra-long cryogenic treatment at - 196 C transforms nearly all residual austenite into martensite.
7. Precipitated nano-carbide particles increase hardness and toughness.
8. Reduce residual stress;
9. The wear resistance is improved remarkably.
Aging treatment
10. Straight Milling Collets Removal of residual internal stress during grinding by over 100 h super-long heat aging.
