The development of science and technology promotes the process of modernization, and the laser marking machine industry has also become a popular industry, which is closer to people's lives and has been widely used in various industries. Innovative products that may completely replace traditional marking processing methods; today we will analyze the laser service life of various laser marking machines. There are more ultraviolet lasers, fiber lasers, CO2 lasers and so on on the market.

The UV laser marking is developed with a 355nm UV laser. Compared with the infrared laser, the machine adopts the third-order intracavity frequency doubling technology. The mechanical deformation of the material is greatly reduced and the thermal influence of processing is small. The effective light-emitting time of the ultraviolet laser is 12,000 to 14,000 hours. According to the average power and working time, the effective working time of the ultraviolet laser is 2 to 3 years. . So does the UV laser need to be replaced after 2~3 years? The answer is no, the effective service life of the UV laser is 2~3 years, it does not mean that the equipment cannot work at all, as long as the escape rate of the UV laser is ensured, the power attenuation is reduced, the service life is prolonged, and a suitable chiller should be configured.

The service life of the fiber laser marking machine is 100,000 hours. Why is the service life of the fiber laser marking machine the longest? This is determined by the performance of the fiber laser itself. The electro-optical conversion rate of the fiber laser is as high as 30%, which can greatly save power consumption and reduce operating costs. The quality of the beam emitted is high, so as to achieve the highest production efficiency; Moreover, its working substance is a lens, which can support long-term excitation. The laser oscillates in the fiber without thermal effect. It only needs to be cooled by air, and does not need to be equipped with a water tank. It does not require frequent replacement of working gas and consumables like gas lasers. Less; cost is lower when laser labels are used in large quantities for different motors. High temperature resistance, wear resistance, anti-corrosion, waterproof, service life of up to 10W hours, reasonable use, under the condition of regular maintenance, there is no problem in using it for 7-8 years.

The CO2 gas inside the CO2 marking machine laser is used as the working substance of the gas laser, and the discharge tube is filled with CO2, helium, nitrogen, hydrogen, xenon, mainly CO2, Others are supplemented; because there are various gases in the working cavity of the CO2 laser, and these can actually be understood as a consumable. A high voltage is applied to the electrode, the discharge tube is discharged, and the galvanometer will have a laser output. The characteristic of CO2 laser is that it has relatively abundant spectral lines, and there are dozens of spectral lines in the laser output near 10 microns. It has relatively large power and relatively high energy conversion efficiency, and the energy conversion efficiency can reach 30~40%, which also exceeds the general gas laser. The service life of the CO2 laser is generally 2W hours.

As mentioned above, any laser marking machine equipment needs our careful maintenance, whether it is UV laser marking machine, CO2 laser marking machine, or fiber laser marking machine. As long as the standard machine is cleaned, cleaned and maintained regularly and correctly, the service life of the equipment will be extended accordingly.
