Causes of Thread Damage to
Hexagon Bolts
1. The tap is not selected. The selection of taps is very particular, and it needs to be selected based on factors such as thread standard, hole size, material used, hole type, and precision tolerance.
2. When tapping the thread, the speed of the tapping is too high and the quality of the coolant is too poor, which leads to problems in the production process of the bolt. Usually, you need to pay attention to controlling the speed of the equipment and ensuring the quality of the coolant.
3. After tapping, there are burrs in the thread turning, which is mainly caused by the failure of the tap.
4. When tapping, there are debris remaining in the thread, and the remaining debris is not cleaned up during cleaning.
5. Rotational instability occurs in the process of tapping and tapping. High automation equipment is mainly used for tapping. If the tapping program is not adjusted well, it will cause unstable rotation.
6. The wear of the tap leads to inaccurate grinding data.
7. The axial pressure is too large.
