Laser cutting machine daily maintenance precautions:

1. Lasers and laser cutting machines need daily cleaning to keep them clean and tidy.

2. Check whether the X, Y, Z axis of the machine can return to the origin, if not, check whether the origin switch position is offset.

3. Laser cutting machine slag drag chain needs to be cleaned.

4. Clean up the sticky material on the filter net of the air outlet in time to ensure that the ventilation pipe is smooth.

5. The laser cutting nozzle needs to be cleaned once every 1 hour and replaced every 2-3 months.

6. Clean the focusing lens, keep the surface of the lens free of residue, and replace it every 2-3 months.

7. Check the cooling water temperature, the laser inlet temperature should be kept between 19℃-22℃.

8. Clean the dust on the heat sink of the water cooler and freeze dryer to ensure the heat dissipation efficiency.

9. Regularly inspect the working state of the regulator, and monitor whether the input and output voltage are normal.

10. Monitor and check whether the switch of the laser mechanical optical brake is normal.

11. The auxiliary gas is the output high pressure gas, and pay attention to the surrounding environment and personal safety when using gas.

12. Switching sequence:

a) Boot: air, water cooling unit, cold and dry machine, air compressor, host machine, laser (note: start low pressure after starting laser, commonly known as high pressure) to bake the machine for 10 minutes if conditions permit.

b) Shutdown: first under high pressure, then low pressure, after the turbine stops rotating without sound, then turn off the laser. Followed by the water cooling unit, air compressor, gas, cold and dry machine, the host can be left behind, and finally close the pressure regulator.
