A laser head collision or even breakage during laser cutting machine operation is a serious equipment malfunction. Quick and correct replacement is crucial to minimizing downtime losses. This article provides a safe and efficient replacement procedure to help you quickly restore production.

I. Emergency Handling and Preparation After a Breakage

Immediate Power Cut: After a collision, immediately disconnect the main power supply to the laser cutting machine to ensure safety.

Comprehensive Inspection: Carefully inspect the damage. In addition to the laser head itself, check the following:

Connecting Components: Check for deformation or cracks in the mounting brackets and connecting plates.

Peripheral Modules: Check for damage to the capacitive sensor, air hoses, and cables.

Lens Condition: Check for cracks or contamination in the focusing lens and protective lens; these must be cleaned or replaced.

Preparation: Prepare a new laser head, an Allen wrench, screw fastener, lint-free paper, and anhydrous ethanol. Wear clean gloves to prevent contamination of optical components.

II. Four-Step Quick Installation Process

Basic Installation: Accurately place the new laser head into the installation position. Pre-tighten all fixing screws by hand to ensure stable installation.

Wiring and Connection: Refer to the drawings and reconnect all electrical, pneumatic, and sensor connections. Ensure plugs are securely locked and air hoses are in place.

Concentricity Calibration (Core Step):

Place a concentricity calibration tool (such as a red light pen or dial indicator) inside the nozzle.

Manually move the laser head and observe the deviation of the laser beam hitting the tool's target center.

Fine-tune the adjusting screws around the laser head until the laser spot is always at the target center.

Finally, tighten all fixing screws diagonally.

Capacitance Height Calibration: Use a thickness gauge or standard plate to recalibrate the capacitive nozzle height of the laser cutting machine to ensure the stability of subsequent cutting.

III. Post-Installation Testing and Precautions

After installation, do not immediately put the machine into production. The following tests must be performed:

No-load Test: Without emitting laser light, run the laser cutting machine through a complex pattern to check for smooth movement and no abnormal noise.

Optical Path Inspection: Test the light output at low power and observe whether the light spot is round and centered.

Trial Cut Verification: Perform a test cut using scrap material to check the quality of the cut surface and whether the lead wire is normal.

Important Note: If you are unfamiliar with the installation process or find any deformation in the mechanical structure, please contact the laser cutting machine manufacturer's professional technicians immediately for handling to avoid secondary damage or performance degradation caused by improper installation. Regularly training operators and checking the equipment path are fundamental ways to prevent collisions.
