Chile Tunnel Project

Project Case: Chile Tunnel Drilling

In a tunnel construction project in Chile, the client’s Atlas Copco rock drills suffered severe wear of impact pistons and damping components due to humid working conditions.
Shaanxi Xianfeng provided replacement impact pistons (P/N: 3115 2971 00) and damping pistons (P/N: 3115 5340 20) made of imported high-strength alloy steel with precision grinding technology.
Field tests proved that our parts delivered superior impact stability, sealing performance, and fatigue resistance, outperforming the OEM standards.
The machines operated smoothly throughout the project, extending maintenance intervals to over 1,200 hours and significantly reducing operating costs.

Highlights:

• High fatigue resistance

• Anti-corrosion treatment for humid environments

• Lower maintenance costs, longer lifespan
