    6kW/8kW Fiber Laser Cutting Head

    Manual focus laser cutting head for processing thin metal sheets and metal tubes with power ratings of up to 6kW/8kW

    These manual-focus heads are designed for everyday production on thin sheet and metal tube at 6–8 kW power levels. They are equipped with an anti-collision protection design with quick reset to bring the laser head back to position after a bump, keeping stoppages short. A lens-contamination alarm flags when the protective window needs cleaning or replacement, which helps protect the internal optics and keeps maintenance costs down. The signal lines are reinforced and well-shielded, so the height follower and other sensors run steadily. Thanks to these laser cutting heads features, they helps every batch cut the same, with clean edges and consistent dimensions.

    Features
    Collision protection with quick reset
    Collision protection with quick reset

    Equipped with a collision protection mechanism to make sure the head gets back to its working position after an impact, which shortens stoppages and helps lower repair costs.

    Contamination monitoring with alarm and safe stop
    Contamination monitoring with alarm and safe stop

    Features a sensor to monitor the protective window and prompts when it’s necessary to change it. If contamination exceeds the limit, the controller issues an alarm and stops the cutting machine to prevent poor cuts and protect the head.

    Built-in capacitive height follower for stable tracking
    Built-in capacitive height follower for stable tracking

    On precision cutting lines, these laser heads integrate a capacitive standoff sensor with reinforced, well-shielded signal paths so height control stays steady and the cut follows smoothly at production speed.

    Automatic laser cutting heads are designed to handle reflective-metal jobs and improve productivity at the same power level. Some of the advantages of these laser scanner cutting heads, include:

    • Stable on reflective metals: Handles brass, copper, silver, polished stainless, and other high-reflectivity alloys by improving energy coupling and controlling back-reflection.
    • Higher precision: Beam scanning enables micron-level accuracy (with proper setup), ideal for fine features.
    • Much faster motion: The galvo scanner moves the beam, not the head, so the spot travels much faster than on a gantry machine. Using the same wattage, you often see multiple times the cutting speed and throughput.
    • Greater thickness capacity at the same wattage: Compared with a standard head of the same power, supports thicker material on reflective cutting processes.
    • Flexible path control: Easily executes complex contours, curves, micro-holes, fine pattern cutting, and engraving by steering the beam rather than the whole head.

    Follow these steps to mount, align, and verify before production:

    • Mount securely. Place the head at the designated location and fasten it with the correct hardware. Make sure the interface is rigid and free of play to prevent vibration or shift during operation.
    • Align and connect. Use alignment tools (or an alignment laser) to set the optical axis and standoff. Check all connections: fiber, assist-gas, air, sensor/IO cables, and water-cooling. Confirm there are no leaks or loose fittings.
    • Power-up and calibrate. Start the cutting machine and run the initial tests and calibration (focus, height-follower, scan field if applicable). Make any fine adjustments needed so the head cuts accurately and repeatably before loading production parts.
