Focus on "heavy weapons of a great power": How can domestic shield machine cutters help tunnel projects run at "China speed"?

In recent years, China has captured 70% of the global market share for shield machines. However, China's ability to independently manufacture and control core components continues to improve. Cutting heads (such as rollers, cutters, and scrapers) are consumables that come into direct contact with the ground and withstand the greatest impact. Their performance and lifespan directly impact the overall project cost and duration.

1.From "Import Dependence" to "Performance Exceeding"

In the past, facing complex geological challenges such as hard rock and ultra-large-diameter tunnels, high-end cutting tools were long dependent on imports. However, today, leading domestic manufacturers, such as our company, have invested heavily in R&D and achieved breakthroughs in materials science, heat treatment processes, and structural design, successfully breaking through technological barriers. Our cutting heads not only meet or even exceed international standards for wear resistance and chipping resistance, but also offer high cost-effectiveness and rapid response.

2. Adaptable Design for Complex Working Conditions

China's geological conditions are known as a "geological museum," boasting an extremely complex landscape, from soft soil to high-strength rock to underwater high-pressure environments. We understand that there is no "one-size-fits-all" cutting tool. Therefore, we provide targeted, customized solutions, including:

Roller Cutters: For high-strength rock, we utilize a special cutter ring alloy formula, optimize the bearing sealing system, and extend cutter change intervals.

Cutter/Scraper Cutters: For mud cake and clay, we optimize cutter angles and surface treatments to improve slag removal efficiency and prevent cutterhead congestion.

Conclusion: The localization of shield machine cutter head accessories not only reduces project costs but also puts the initiative in our own hands, providing a solid foundation for the smooth implementation of major national projects. Going forward, we will continue to focus on cutting-edge technologies, providing higher-quality cutting tools to help tunnel projects achieve even faster "China speeds."
