What is the reason for the abnormal fracture of the drill tail?
2023-06-30
The drill tail is a key part of the hydraulic rock drill to transmit rotation and impact energy. During the operation, it bears the complex load transmitted by the impact piston and rotary motor of the rock drill. The typical failure of the drill tail is usually abnormal fracture. Generally, the working time is less than 10 shifts, and the drill tail breaks at the root of the thread or the thread.
