Fiber laser marking machines and carbon dioxide laser marking machines on the market are cheap, have a long service life, are easy to maintain, and have low environmental requirements. So why are UV laser marking machines so expensive? In comparison, the service life is shorter, and maintenance is more careful? Today, the editor of Chuangxuan Laser will introduce to you the reasons why the UV laser marking machine is expensive.
The structure of the ultraviolet laser marking machine is the same as that of the fiber laser marking machine. It consists of ultraviolet laser, galvanometer, lens, industrial computer, control card, workbench casing, electronic control device, power supply, red light, pedal, and It is composed of surgical mirrors and other original parts, so how many times the price of the UV laser marking machine is the price of the fiber laser marking machine?
The optical components of fiber laser marking machine and ultraviolet laser marking machine cannot be used in common. The wavelength of ultraviolet laser is 355nm, and the wavelength of fiber laser is 1064nm. The wavelength of ultraviolet laser is the wavelength after frequency multiplication on the basis of 1064nm wavelength through technology. The technical difficulty is higher, which causes the price of UV lasers to be several times that of fiber lasers, and the relative stability of fiber lasers is also poor;
The galvanometer and lens of the UV laser marking machine are different in thickness and material than the fiber laser marking machine, so they cannot be used universally. The galvanometer and lens of the UV laser marking machine are also more expensive. Of course, the conventional galvanometer on the market The price difference between the lens and the two equipment is not big, the main price difference is between the ultraviolet laser and the fiber laser.
On the other hand, UV laser marking machines have relatively higher environmental requirements, especially water-cooled lasers, which need to be kept at a constant temperature. In addition, the stability of the UV laser marking machine is not as good as that of the fiber laser marking machine. It requires manual after-sales assistance, which increases labor costs. The fiber laser marking machine does not even need to be handed over to the machine, and only needs to be operated remotely. It can be seen how strong the stability and applicability of the fiber laser marking machine are.
The overall combination makes the price of UV laser marking machine relatively expensive. On the one hand, it is reflected in the high cost of UV lasers, and on the other hand, it is manifested in labor costs. The stability and life of UV laser marking machines are not as good as optical fibers. The laser marking machine needs to provide after-sales service, especially after a long time of use, the power of the ultraviolet laser decays relatively quickly, and the labor cost is also up.
So the UV laser marking machine is expensive, what is the current price? It is mainly determined by the price fluctuations of UV laser manufacturers. For example, in the early years, there was no UV laser manufacturer in China, and a 3w imported UV laser also required hundreds of thousands. With the breakthrough of domestic technical barriers, 3w UV lasers The price has also dropped significantly. So far, only tens of thousands of renminbi are used for pure imported top-level ultraviolet lasers. Therefore, the price trend of UV laser marking machines currently depends on the development of the overall domestic UV laser manufacturers and the development of market applications.
The working mode of hand-held fiber laser welding machine, hand-held welding is flexible and convenient, and the welding distance is longer. Replace the previous fixed light path with a handheld welding gun. The handheld fiber laser welding machine is mainly used for laser welding of long-distance and large workpieces. The heat-affected area during welding is small and will not cause work deformation, blackening, back...2020-10-26 View content
