    Features
    Nozzle temperature monitoring
    Nozzle temperature monitoring

    High-temperature alarm automatically issues a shutdown command that ensures timely stop and alerts the operator to troubleshoot, preventing processing defects.

    Real-time height monitoring and control (with system support)
    Real-time height monitoring and control (with system support)

    Continuous transmission of nozzle temperature data dynamically adjusts cutting height maintains a consistent distance between nozzle and workpiece for stable cutting quality.

    Focus position control (with system support)
    Focus position control (with system support)

    Real-time lens temperature control allows automatic focus adjustment that prevents focus drift caused by lens heating, ensuring uniform cutting performance.

    Built-in gas pressure monitoring (with system support)
    Built-in gas pressure monitoring (with system support)

    Alarms are triggered if cutting gas pressure is abnormal, preventing damage and poor cutting caused by low or missing gas pressure.

    Automatic gas flow adjustment & pressure control (with system support)
    Automatic gas flow adjustment & pressure control (with system support)

    Detects differences between actual and set cutting gas pressure, and calibrates pressure automatically to ensure consistent cutting quality and protecting the head.

    Leakage detection & warning signal
    Leakage detection & warning signal

    Issues an alarm if the laser protection window seal fails and reminds operators to service or replace parts, preventing internal lens contamination.

    Collision protection for safety
    Collision protection for safety

    Built-in sensor with dedicated blowing assembly that protects the laser head upon collision, while triggering an immediate shutdown signal.

    Piercing monitoring for higher efficiency (with system support)
    Piercing monitoring for higher efficiency (with system support)

    Monitors piercing results in real time. Cutting begins immediately after penetration, eliminating delays and boosting productivity.

    Lens contamination monitoring & warning signal
    Lens contamination monitoring & warning signal

    Alerts when lenses become contaminated, with both warning and shutdown modes. This prevents poor cutting quality and laser head damage by ensuring timely lens replacement.

    Our high-power laser cutting head is designed for high-performance in thick plate processing. It integrates gas pressure monitoring, leakage detection, piercing detection, and nozzle temperature monitoring. These functions simplify thick plate cutting, improve stability, and allow efficient operation with easier maintenance.

    The specialized tube and profile laser cutting heads are capable of processing round tubes, square tubes, and H-beams. Suitable materials include carbon steel, stainless steel, and other industrial-grade metals.

    • Before use, wrap the head with protective tape to prevent dust accumulation in gaps during maintenance.
    • Do not attempt to clean or disassemble internal lenses if they become dirty or damaged, as this may cause further contamination. It is recommended to replace them directly.
    • Replacement of protective lenses, collimation lenses, and focusing lenses must be performed in a cleanroom environment (class 1000 or above).
    • When inspecting lenses, first use white paper to check for black spots on the red laser beam. Then, at low power, use black photosensitive paper to examine the beam spot. Finally, remove the lens and inspect it under a microscope for accuracy.
