It can be mainly used to cut some non-metallic materials, such as paper, bamboo and wood products, acrylic, rubber, etc. The cutting thickness depends on the actual cutting speed and cutting quality. Generally, the slower the cutting speed is, the thicker the cutting will be, but there will be melting edges at the cutting edge. Theoretically, the 25W laser tube has low power and small light spot, which is suitable for carving and not suitable for cutting. If it is used to cut materials, it is necessary to use higher power CO2 glass laser tubes, such as 80W, 100W, 130W and 150W CO2 laser tubes.
Laser is the core of laser equipment, and its type and quality directly determine the quality of laser processing equipment. Especially in the field of medium and small power laser equipment manufacturing, CO2 gas laser is the most widely used laser. At present, the main applications are glass sealed CO2 laser and CO2 RF metal laser.
Disadvantages of glass tube sealing off CO2 laser
Although the price of the traditional glass tube sealed CO2 laser is relatively cheap, its use failure rate is high, its life is short, its volume is large, its beam mode is poor (the slit is thick), its light output response speed is slow, and it cannot output light at low power (the power adjustability is poor, and the processing effect of the same power laser on different materials varies greatly). These shortcomings are not only increasingly difficult to meet the production and processing needs, but also restrict its long-term development.
For example, in terms of service life, the life of the glass tube sealed CO2 laser is generally about 6000 hours, and production will be affected due to failures. In terms of use cost, the use cost of glass tube sealed CO2 laser is about 1 yuan per hour. In addition, it is also a consumable. The longer the use time is, the higher the relative cost is. With the gradual improvement of production requirements, this kind of laser has become increasingly difficult to meet the needs of industrial production.
advantage
CO2 RF metal laser is one of the most rapidly developing technologies in the industrial laser market in recent years, and is considered to be the best substitute for glass tube sealed CO2 laser.
It adopts a fully metallized structure, featuring small size, full closure, compact device, sealed off operation, maintenance free, low use cost, excellent modulation characteristics, high output beam quality (more than 3 times finer than glass tube), high injected power density, low operating voltage, adjustable output power, excellent power stability, high operation reliability, and more importantly, The CO2 RF metal laser also has the advantages of long service life (generally more than 20000 hours), low maintenance cost, reusable after inflation, and no replacement.
In addition, among all kinds of industrial lasers, CO2 lasers have the lowest output cost per watt and high plug efficiency, ranging from 10% to 12%. Their applications include high-speed cutting, engraving and welding of flexible materials, non-metallic solid materials and metal materials. These advantages make CO2 RF metal lasers very suitable for industrial continuous production.
