Judging from the application fields of modern laser cutting and welding machines and the technical requirements put forward by users,
JH CO2 have 30W 40W 50W 60W 80W 100W 130W 150W the future development direction of laser cutting and welding is undoubtedly high power, large size, high efficiency, one-step molding and high intelligence.
cutting machine and fiber laser cutting machine
Here, the differences between cutting machine and fiber laser cutting machine are mainly described:
First, as the mainstream 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 .. Fiber laser has obvious advantages in cutting thin plates within 4mm, and its quality is poor due to the influence of solid laser wavelength. The laser cutting machine is not universal either. The wavelength of the is 10.6um, and the wavelength of the solid laser such as YAG or fiber laser is 1.06um. The former is easy to be absorbed by non-metals and can cut non-metal materials such as wood, acrylic, PP and plexiglass with high quality, while the latter is not easy to be absorbed by non-metals and therefore cannot cut non-metal materials. However, both lasers are helpless when they encounter high-reflection materials such as copper, silver and pure aluminum.
Secondly, it is precisely because the wavelengths of CO2 laser and fiber laser differ by an order of magnitude, the former cannot be transmitted by fiber, and the latter can be transmitted by fiber, greatly increasing the flexibility of processing. In the early days before the introduction of fiber laser to the market, in order to realize three-dimensional processing, we used optical joint technology to guide CO2 laser tube to the surface of three-dimensional curved surface through a highly precisely matched dynamic combined mirror system, thus realizing three-dimensional processing of . This technology is mainly controlled by a few developed countries in Europe and the United States because of its high price and high maintenance requirements. While the market share of fiber laser is gradually expanding, it has gradually lost its market. However, the degree of flexibility of fiber laser has increased unprecedentedly because it can be transmitted through optical fiber, especially for the automobile industry, because it is basically about 1mm thin-plate curved surface processing, the fiber laser with the same flexible robot system has low cost, few fault points, convenient maintenance and extremely fast speed, and firmly occupies this market.
Thirdly, the photoelectric conversion rate of fiber laser is as high as 25 %, while the photoelectric conversion rate of is only about 10 %. The advantages of fiber laser are quite obvious in terms of electricity consumption and supporting cooling system. If more fiber laser manufacturers are available, the price will be more appropriate and the thick plate cutting process will be solved, the threat to will be huge. However, as a new laser technology, fiber laser is far less popular than r, and its stability, reliability and convenience of after-sales service still need long-term observation by the market.
It is worth mentioning that according to international safety standards, laser damage is classified into four levels, is the least harmful level, while fiber laser is the most harmful level because it is harmful to human eyes due to its wavelength. For safety reasons, fiber laser processing needs a totally enclosed environment.
In addition, the flexible processing system of fiber laser and robot has a long standing in the automobile industry and its supporting industries, and has been monopolized by foreign integrators in the past. In recent years, due to the financial crisis and the continuous improvement of the production technology in the automobile industry, especially the research on the technology by domestic laser technology high-end manufacturer Rospert Laser with the support of the national policy, many foreign middle and high-end brands and national brands have first tasted crabs. The proud and mysterious veil of foreign super-high prices has been lifted and torn. Spitt laser has provided car white body welding, car dashboard laser weakening, car airbag laser welding, robot flexible cutting such as car bumper, car door and center pillar, car bumper laser welding, car exhaust pipe on-line welding system, car gear changing set laser automatic cutting equipment and so on for car users in recent years. It has produced stably and efficiently at the user's site for 24 hours, making users praise JH LASER while also making foreign integrators shout " wolf!"!
To sum up, the direction of laser application should be the application of high-power on more stable, large-scale and faster machine tools. For curved surface processing below 2mm, fiber laser is more advantageous.
