Retention Knob for BT 45° Pull Stud

Retention Knob for BT Tool Holder 45° Pull Stud,BT pull stud Aging treatment 20-40 h super-long heat aging removes residual internal stress during grinding. Deep cooling treatment and thermal aging treatment can reduce residual stress and improve durability and accuracy stability.Adopt surface coating technology to improve the anti-wear ability of the surface, better anti-rust and anti-corrosion effect, more stable accuracy, smoother surface and more beautiful appearance.

accuracy of stability. pull stud BT40 Cryogenic treatment
1. The 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.
