    TBMs: Built to Last!

    Refurbishing Tunnel Boring Machines (TBMs) and Micro-TBMs (MTBMs) is critical to extending their operational lifespan and maximizing your return on investment. At Tunnel Saz Machine Co. (TSM), we breathe new life into these complex machines which are used for underground construction projects, such as tunnels for transportation, utilities, and mining, ensuring they perform like new while meeting modern safety and efficiency standards.

    The Refurbishment Process

    1. Assessment & Disassembly
    • Comprehensive Inspection: Evaluate wear on critical components like cutter heads, shields, thrust cylinders, and control systems.
    • Disassembly: Methodically dismantle the TBM/MTBM to inspect every subsystem.
    1. Component Refurbishment
    • Cleaning & Repair: Remove debris, replace worn parts (bearings, seals), and restore structural integrity.
    • Technology Upgrades: Integrate modern software, sensors, or cutting tools to enhance performance.
    1. Reassembly & Testing
    • Precision Rebuild: Reassemble components to OEM specifications, ensuring optimal alignment.
    • Rigorous Testing: Validate hydraulic, electrical, and mechanical systems under simulated operational stress.
    1. Compliance & Safety
    • Environmental Standards: Ensure adherence to emissions and waste disposal regulations.
    • Safety Protocols: Certify all systems meet the latest industry safety guidelines.
