Features：
- Material: SUJ2
- HRC: HRC44-48
- Inner hole grinding for many times, so as to reach Ra0.4, has a mirror effect
The design of the convex platform in front of the collet can prevent dust and chip getting into the collet when processing, prolong the tool's life. - End and the cylindrical are grinding for many times, can reach Ra0.4, has a
mirror effect. - Surface"environmental protection", special coating surface treatment, improve the hardness and endurance of the surface,cleaness better, accuracy stable, surface more smooth, antirust, feel comfortable, appearance nice.
- The desing of 4º collet, more clamping force, to improve seismic performance.
Exquisite processing technology:
- -185°C long cryogenic, nearly of the residual austenite into martensite.
- Carbide precipitation of Nanoscale particles, increasing the hardness and toughness.
- Reducing residual stresses.
- Wear resistance significantly improved.
- Thermal aging processing ≥ 100h long stereotyped thermal limitation removal of grinding residual stress.
