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.




BT40 pull stud is a specific type of pull stud used in CNC milling machines that have a BT40 spindle taper. The pull stud is a critical component in the tool holding system, as it is responsible for securely clamping the tool holder in place during machining operations.

The BT40 pull stud is designed with a threaded end that screws into the tool holder's retention knob. The other end of the pull stud has a tapered shank that fits into the spindle taper of the milling machine. When the pull stud is properly tightened, it creates a strong connection between the tool holder and the spindle, ensuring that the tool remains securely in place during cutting operations.

BT40 pull studs are made from high-quality steel and are heat-treated to provide maximum strength and durability. They are typically black oxide coated to resist corrosion and wear. The pull studs are also precision ground to ensure accurate alignment and proper fit within the tool holder and spindle taper.

It is important to use the correct BT40 pull stud for your specific CNC milling machine, as different machines may have different pull stud designs and dimensions. Using the wrong pull stud can lead to poor tool holding performance, increased tool wear, and potential safety hazards.

When installing or replacing a BT40 pull stud, it is essential to follow the manufacturer's instructions and use the recommended torque specifiCATEEions. Over-tightening or under-tightening the pull stud can result in improper tool holding and reduced machining accuracy.

Overall, the BT40 pull stud is a critical component in CNC milling machines with BT40 spindles, ensuring secure and accurate tool holding during machining operations
