Fiber Laser Cutting Machine VS CO2 Laser Cutting MachineTina
If you’re looking to mark metal, what you need to buy is a fiber laser. If you’re looking to mark organic materials like textiles, wood, or cardboard, a CO2 laser is the best choice.
If your application is laser cutting of metals, you’ll most likely need a high-power CW (continuous wave) fiber laser. For other materials like plastics and rubber, it can be one or the other.
The main difference that determines the type of materials each laser can process is the wavelength. A fiber laser usually has a wavelength of 1,060 nm while CO2 lasers have wavelengths in the 10,600 nm range. In general, fiber lasers have many advantages over CO2 lasers.
CO2 Laser Cutting Machine
As traditional laser cutting and welding equipment, CO2 lasers are used, which can stably cut carbon steel within 20mm, stainless steel within 10mm, and aluminum alloy below 8mm. The fiber laser has obvious advantages when cutting thin plates within 4mm, and the quality of cutting thick plates is poor due to the influence of the wavelength of the solid-state laser. The laser cutting machine is not the same. The wavelength of CO2 laser is 10.6um, and the wavelength of solid lasers such as YAG or fiber laser is 1.06um. The former is relatively easy to be absorbed by non-metals and can cut wood, acrylic, PP, plexiglass, etc. with high-quality Non-metallic materials, the latter is not easily absorbed by non-metals, so non-metallic materials cannot be cut, but the two lasers have nothing to do when they encounter high-reflective materials such as copper, silver, and pure aluminum.
What is the difference between Fibre laser and CO2 laser?
It is precise because the wavelengths of CO2 and fiber laser differ by an order of magnitude.The former cannot be transmitted by optical fiber, while the latter can be transmitted by optical fiber, which greatly increases the flexibility of processing. In the early days before the launch of fiber lasers on the market, in order to achieve three-dimensional processing, we used optical joint technology to guide the CO2 laser to the three-dimensional curved surface through a highly precise coordinated dynamic combined mirror system to achieve the three-dimensional processing of the CO2 laser. This technology is because of the domestic The limitations of precision processing technology are mainly in the hands of a few developed countries in Europe and America, which are expensive and require high maintenance. As the market share of fiber lasers is gradually expanding, it has gradually lost its market. Because fiber laser can be transmitted through optical fiber, the degree of flexibility is improved, especially for the automotive industry, because it is basically a thin plate surface processing of about 1mm, the fiber laser cutting machine is matched with the same flexible robot system, and the cost is low, and the point of failure is low. Less, easy to maintain, extremely fast, and do my part to occupy this market steadily.
The photoelectric conversion rate of fiber laser is as high as 25%, while the photoelectric conversion rate of CO2 laser is only about 10%. The advantages of fiber laser cutting machines in terms of electricity consumption and supporting cooling systems are quite obvious. More, the price is more appropriate, and the thick plate cutting process is solved, the threat to the CO2 laser will be huge. However, as emerging laser technology, fiber laser is far less popular than CO2 laser. Its stability, reliability, and convenience of after-sales service are yet to be observed by the market for a long time.
