Precision 0.008mm Spring ER Collet is the most widely used clamping tool in the world.Made from Alloy spring steel and fully hardened,the ER collets are ideal for many machining applications including boring, milling, reaming, tapping and grinding.
1. Er Collet Material: SUJ2; 42CrMo;
2. ER COLLET Hardness: 46-50HRC;
3. ER Collet inner hole can be grinded many times, reaching Ra0.4, which has a mirror effect.
4. ER Collet Grinding process is adopted for hollow slot of cylinder clamp, which is more suitable for high-speed machining.
5. External circle and end surface can be grinded many times, reaching Ra0.4, which has a mirror effect.
6. Surface "environmental protection" special coating treatment, improve surface hardness, wear resistance, improve cleanliness, more stable accuracy, smoother surface, better rust and corrosion resistance effect, feel more comfortable, appearance more beautiful.
7. ER Collet Cryogenic treatment
1. Ultra-long cryogenic treatment at - 185 C transforms nearly all residual austenite into martensite.
2. Precipitated nano-carbide particles increase hardness and toughness.
3. Reducing residual stress;
4. The wear resistance is improved significantly.
8. Aging treatment
Removal of residual internal stress during grinding by over 100 h super-long heat aging
