How to replace laser cutting machine consumables

Laser cutting machine consumable replacement typically involves several key components, and the general steps and precautions are as follows:

1. Focusing Lens Replacement:
   • Shut off the power supply to the laser cutting machine, ensuring the equipment is in a safe state.
   • Disassemble the protective lens tube or focusing lens tube according to the manufacturer's instructions.
   • Carefully remove the old focusing lens using specialized tools, avoiding direct contact with the lens surface to prevent scratches.
   • Clean the inside of the lens barrel, then install the new focusing lens, ensuring it is placed in the correct direction and position.
   • Reinstall the lens tube and ensure it is tightened properly.
2. Protective Lens Replacement:
   • Similarly, turn off the power and disassemble the protective lens assembly as directed.
   • Gently remove the old protective lens without directly touching the lens surface.
   • Clean the lens holder and then install the new protective lens, ensuring it is sealed well to prevent dust and moisture ingress.
3. Nozzle Replacement:
   • Shut off the machine and evacuate the auxiliary gas.
   • Remove the old nozzle using the appropriate tools, checking for blockage or wear in the nozzle hole.
   • Install the new nozzle, ensuring the distance from the focusing lens is correct, and reconnect the auxiliary gas line, ensuring airtight sealing.
4. Ceramic Ring Replacement (applicable only to certain laser cutting machines):
   • After turning off the power, remove the old ceramic ring following the specified procedure.
   • Replace with a new ceramic ring, ensuring a tight fit with no gaps around the cutting head.
5. Reflection Mirror Replacement:
   • Power off the machine and locate the reflection mirror as per the manual instructions.
   • Carefully take out the old reflection mirror, clean the mirror bracket, and install the new mirror, ensuring the mounting angle is accurate.

After each replacement of consumables, it's crucial to perform necessary adjustments and tests to ensure the laser cutting machine operates normally and delivers satisfactory cutting results. Always adhere to the detailed operating instructions and safety measures provided by the laser cutting machine manufacturer, as different models may have unique replacement procedures and requirements. Furthermore, regular maintenance and timely replacement of consumables help extend the lifespan of the laser cutting machine and maintain its efficiency.
