Factors Affecting the Service Life of Industrial Ultraviolet Lasers

The lifespan of an industrial ultraviolet laser is affected by three factors: maintenance, the environment in which the machine is used, and the habits of the operator.Regular cleaning of optical components, control of temperature and humidity, and control of dust pollution are fundamental, and setting reasonable working parameters and standardizing the procedures for switching the equipment on and off can significantly extend the lifespan of the equipment.I would recommend that you combine your daily maintenance plan with the environmental improvements I have suggested to ensure long-term stable operation of your UV laser marking machine.

Maintenance is the key.

The life of a UV laser engraving machine is directly related to its daily maintenance.Many users tend to neglect to check the optical path and the heat dissipation system, which leads to a rapid decline in the laser's power.It is recommended that the optical lenses be cleaned once a month, and that the cooling system be inspected for blockages every three months.

How much of an impact does the environment have?

You can't be lax about controlling temperature and humidity.

Industrial-grade ultraviolet lasers are most afraid of high temperature and high humidity.The temperature in the workshop should be kept between 15 and 25 degrees Celsius, and the humidity should not exceed 60 %.Some factories don't use air conditioners to save electricity, but then condensation forms inside the equipment and optical components fail after two or three months.

We have to take the strongest possible measures to prevent air pollution.

In a metal processing shop, dust and oil mists are the laser's "invisible killers.Adding a special dust cover or isolating the operating room can greatly reduce the chances of contamination to the lenses.The most extreme case I've seen was of a machine that was used without protection for half a year and ended up being scrapped.

How long they last depends on how you use them.

Don't be too radical in the parameters.

Some operators, in order to improve efficiency, have set the power to 100 % and run the machines continuously.In fact, the most cost-effective operating point for a UV laser is 80 % of capacity. This ensures that the marking effect will be satisfactory, while also extending the life of the core components.Remember, equipment is like people, and cannot be kept under constant strain.

There is a certain order to be observed when turning on and off the machines.

Power failures and violent shutdowns are the most likely causes of damage to the laser power module.The correct method is to shut off the laser output first and then wait three minutes for the cooling system to run.One customer was always pulling the circuit breaker, and we had to replace the power module three times.
