- Research Results
- After visually inspecting the shield machine bits for tunnel construction, etc., we established a method to judge whether the strength of a bit is sufficient by diagnosing the bonding surface of cemented carbide and the foundation by nondestructive inspection. Reused bits will be good for new construction works.
