Precautions for the maintenance of laser engraving and cutting machine

1. The fulcrum of laser tube installation should be reasonable, and the fulcrum should be at 1/4 of the total length of the laser tube, otherwise the laser tube spot mode will become bad, and some spots will become several points after working for a period of time, resulting in the decline of laser power and unable to meet the processing requirements, resulting in continuous tube replacement

2. The water protection system should be checked and cleaned frequently. The cooling water often cannot be flushed. The water protection float switch or the water protection float switch does not reset, and the short-circuit method cannot be used to solve the urgent problem. The circulating cooling water quality is better. After the aluminum oxide in the water nozzle is too serious, the dirt in the water pump, water pipe and water protection must be cleaned regularly after use for a period of time, otherwise it is easy to cause the laser tube to burst or the cold water head to fall off

3. The cooling system should be grounded, the water tank and water path should be cleaned and checked frequently, and the temperature control point of the refrigeration temperature control water tank should be reasonable, otherwise the laser tube will be damaged and dewed, which will affect the laser power decline, the cold water head of the tube shell will fall off, and the service life will be greatly shortened, so that it cannot work, resulting in the replacement of the laser tube

4. Keep the air suction device for a period of time (fans and air ducts) and regularly check and clean it up, otherwise a lot of smoke and dust will not be discharged, which will seriously and quickly pollute the reflective and focusing lenses and laser tubes, making all mechanical and electronic components easy to oxidize, resulting in poor use effect of the equipment

5. Check the focusing lens and reflector. After working for a period of time, the lens frame will heat up, and the surface of the lens will change color, film and rust; Film removal and cracking are the objects to be replaced, especially when many customers use large air pumps and air compressors, so that water will soon accumulate on the focusing lens. The patented high-power die-cutting plate laser cutting machine developed by the company has completely solved the difficult problem of eliminating water in the optical path

6. The working environment of the machine should not be too bad. If the ambient temperature is higher than 30 degrees and lower than 18 degrees, there is too much dust and serious air pollution, so the machine is seriously damaged and the failure rate will continue to rise; Electrical accessories are easy to go wrong in humid environment. Therefore, the customer is reminded to improve the working environment and maintain the machine frequently

7. Electric power should be matched. The whole transfer switch should be turned to the "loading" position, and the power distribution and contact points of all parts of the equipment should be good (fans, water coolers, laser machines, laser power supplies, computers should be powered independently)

8. The working current of the laser tube should be reasonable, and it cannot work at the light intensity for a long time; To rationalize the application of laser and save laser energy; The light path system should be clean and correct, otherwise the laser tube will age and crack prematurely, so the working diagram of the laser machine 8 metallic paint and pearlescent effect the use time intensity of the spray free material on the vehicle should be adjusted to% and then the working speed should be adjusted according to the material, so that the best working state of the laser tube is that the wire should be more than 150 cm from the ground

9. The bottom plate and the processed material should be flat, otherwise the focal length will be inconsistent, and some places will not be cut through. In this way, the light intensity will be increased, which will also lead to the rapid aging of the laser tube

10. The heat dissipation of the laser power supply should be smooth, otherwise once the working current is adjusted by more than 50%, the temperature will rise very high, so the failure rate of the laser power supply will increase
