Key Components:

• QBH Interface: Connection point for the fiber laser cable.
• Collimating Module: Contains the collimating lens (D30 F100) to parallel the laser beam.
• Focusing Driver Module: Houses the focusing lens and the auto-focus mechanism.
• Protective Lens Module: Contains the protective windows (upper: 24.9x1.5mm, lower: 27.9x4.1mm) to shield internal optics.
• Nozzle Module: Directs the assist gas and shapes the laser beam for cutting.
• Water Pipe Connections: For cooling the laser head.
• Assist Gas Inlet: For connecting the assist gas supply.

3. Setup and Installation

Proper installation is critical for the performance and safety of the laser cutting head. Ensure all connections are secure and follow safety guidelines for laser equipment.

1. Mounting the Laser Head: Securely attach the BM110 laser cutting head to the designated mounting bracket on your fiber laser cutting machine. Ensure it is stable and correctly aligned.
2. Connecting the Fiber Laser: Connect the fiber laser cable to the QBH interface on the top of the laser head. Ensure the connection is clean and tight to prevent power loss or damage.
3. Water Cooling Connections: Connect the water cooling pipes to the designated water pipe inlets/outlets on the laser head. Ensure a continuous flow of clean, temperature-controlled cooling water as per machine specifications. Refer to Figure 2.1 for water pipe locations.
4. Assist Gas Connection: Connect the assist gas supply line to the assist gas inlet (Φ10mm) on the side of the laser head. Ensure the gas pressure is within the recommended range (≤ 30 bar). Refer to Figure 2.2 for assist gas inlet location.
5. Electrical Connections: Connect any necessary electrical cables for the auto-focus system and sensors according to your machine's wiring diagram.
6. Nozzle and Ceramic Installation: Install the appropriate nozzle and ceramic ring for your cutting application. Ensure they are seated correctly and securely.
7. Initial Inspection: After installation, visually inspect all connections for leaks, loose fittings, or damage.

4. Operating Instructions

This section provides general guidelines for operating the BM110 laser cutting head. Always refer to your specific laser cutting machine's control software manual for detailed operation procedures.

1. Power On: Ensure all cooling systems, assist gas, and the fiber laser source are powered on and functioning correctly before activating the laser head.
2. Parameter Setting: Set the cutting parameters (laser power, cutting speed, assist gas type and pressure, focus position) in your machine's control software according to the material and thickness being cut.
3. Auto-Focus Activation: The BM110 features an auto-focus system. Activate this function through your machine's control software. The system will automatically adjust the focus position within its range of -12mm to +10mm with 0.05mm accuracy.
4. Test Cut: Perform a test cut on a scrap piece of the material to verify cutting quality and adjust parameters if necessary.
5. Monitoring: During operation, monitor the cutting process for any anomalies. Ensure proper assist gas flow and cooling water temperature.
6. Emergency Stop: Be familiar with the emergency stop procedures for your laser cutting machine.

Important Considerations:

• Always wear appropriate laser safety eyewear.
• Ensure the work area is well-ventilated to remove fumes.
• Maintain the recommended assist gas pressure for optimal cutting results and to prevent back-splatter damage to optics.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your laser cutting head. Perform these tasks with the laser system powered off and locked out.

1. Protective Window Inspection and Cleaning:
   • Regularly inspect the protective windows (upper: 24.9x1.5mm, lower: 27.9x4.1mm) for dust, debris, or damage.
   • To clean, use a lint-free optical wipe and optical-grade cleaning solution. Handle with care to avoid scratching.
   • Replace protective windows if they are scratched, pitted, or show signs of contamination that cannot be cleaned. The drawer-type lens holder facilitates easy replacement.
2. Nozzle Inspection and Replacement:
   • Inspect the nozzle tip for wear, deformation, or blockages.
   • Clean any accumulated spatter from the nozzle.
   • Replace the nozzle if it is damaged or worn, as this affects cutting quality and gas flow.
3. Ceramic Ring Inspection:
   • Check the ceramic ring for cracks or damage. A damaged ceramic ring can lead to unstable cutting and poor performance.
   • Replace if damaged.
4. Cooling System Check:
   • Ensure the cooling water is clean and free of particles.
   • Verify that the water flow rate and temperature are within the manufacturer's specifications.
   • Periodically clean or replace water filters if applicable.
5. General Cleaning: Keep the exterior of the laser head clean and free of dust and debris.
