BT pull stud Product introduction:
Cnc Tools Holder Pull Stud Material: 20CrMnTi;
Bt30 Pull Stud Carburizing depth: > 0.8;
BT pull stud Head hardness: 54-57HRC;
Cnc Pull Stud The hardness of threads and other parts is low: 35+5HRC,( 59169094, 59169067, 59168926, 57678307, 57086549,the core hardness of protective handle threads can withstand impact);

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.

Aging treatment
20-40 h super-long heat aging removes residual internal stress during grinding.




Products advantages
1. After heat treatment, and then quenching, cleaning, tempering, pull the nail out hard, not easy to fracture.
2. the use of flexible steel material.
3. BT conical shell cutter shank: 30, 50, 40
4. suitable milling cutter: 13mm-50mm
5. Precision is less than 0.01mm balance 8000rpm. High accuracy can also be made according to your requirements. (g6.3/12000rpm, G2.5 / 20000) 48-55hrc hardness.
6. suitable for pulling the stub with the milling cutter disk is also required.

BT pull studs are a type of tool holder accessory used in machining operations. They are designed to secure the tool holder to the spindle of a machine tool, such as a milling machine or machining center.

BT pull studs have a specific design that allows them to be quickly and securely inserted into the spindle. They typically have a threaded end that screws into the spindle, and a flange or collar that provides additional stability and support.

The pull stud is an essential component in the tool holder system, as it ensures proper alignment and transfer of cutting forces between the tool holder and the spindle. It also allows for quick tool changes and ensures that the tool holder remains securely in place during machining operations.

When selecting BT pull studs, it is important to consider factors such as the size and type of the machine tool spindle, as well as the specific tool holder being used. Different machine tool manufacturers may have their own specific requirements for pull stud dimensions and specifiCATEEions.

Overall, BT pull studs play a critical role in the efficient and accurate operation of machine tools, and are an important component in the tool holder system.
