Shaanxi Xianfeng Rock Drilling Machinery Equipment Co., Ltd.

Project Case: Kazakhstan Copper Mine In a large copper mining project in Kazakhstan, the client’s Montabert HC95 rock drill experienced frequent wear of the front guide and rotary sleeve, leading to reduced drilling efficiency. Shaanxi Xianfeng Rock Drilling Machinery Equipment Co., Ltd. quickly responded and supplied replacement front guides (P/N: 101015632) and rotary sleeves (P/N: 86746450) specifically designed for the HC95 drill. By optimizing the alloy composition and heat treatment process, the wear resistance was improved by 35%, and the lifespan was extended to 1.5 times that of OEM parts. The client reported significantly reduced downtime and a 20% increase in drilling efficiency, enabling the project to meet its deadlines ahead of schedule. Highlights: High-wear-resistant alloy material Perfect OEM compatibility Improved performance and durability

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

On November 5, 2025, our company received an urgent report from an overseas customer regarding an Epiroc 18U hydraulic rock drill. After performing the 800-hour maintenance package, the customer noticed abnormal gearbox overheating during operation.   Upon receiving the feedback, we immediately activated our after-sales emergency response protocol and dispatched a professional service engineer to the site. Through detailed inspection and performance testing, it was determined that the gearbox spacer adjustment gap was too small, restricting oil flow and causing the temperature to rise excessively.   After readjusting the spacer clearance and running verification tests, the machine resumed normal operation with gearbox temperature back within the safe range. The customer expressed great satisfaction with our quick response and technical expertise.   This incident once again demonstrates our company’s strong capability in rock drill maintenance, troubleshooting, and customer service. We remain committed to the principle of “Quality First, Service Always,” delivering reliable equipment solutions to customers worldwide.
