High maintenance requirements for fiber laser cutting machine
The computer of the fiber laser cutting machine should be disinfected in time, and it is better to use a dedicated U disk to import the drawings. 3. Maintenance every half month 1. Replace the pure water or steam-controlled water in the water tank, wipe the sticky substance in the water tank with a clean cloth, and clean the filter element in the water tank and the filter element in the filter (filter The filter element in the device needs to be replaced every month) At the same time, clean the evaporator and the condenser (first open the side door of the water tank, and then blow the condenser upward with an air gun). Consumption). 2. Wipe the screw guide rail clean and smear it with lubricating oil, and move it back and forth several times at low speed until the oil completely penetrates into it. (Dust on the screw and guide rail will cause serious wear, affect the cutting accuracy, and even produce noise) 4. Monthly maintenance 1. Check the screw seat and the screw of the motor seat next to the two shafts, and the coupling screw CO2 laser cutting machine Comparison with fiber laser cutting machine Judging from the application fields of modern laser cutting and laser welding machines and the technical requirements proposed by users, the future development direction of laser cutting and welding is undoubtedly high power, large format, high efficiency, one-time forming, high Intelligent.
First of all, the mainstream traditional laser cutting and welding equipment all use CO2 lasers, 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 it has poor quality when cutting thick plates due to the influence of the wavelength of the solid laser. The laser cutting machine is not the same. The wavelength of CO2 laser is 10.6um, and the wavelength of solid laser 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. However, the two lasers have nothing to do when they encounter high-reflective materials such as copper, silver, and pure aluminum. Secondly, it is precisely because the wavelengths of CO2 and fiber lasers differ by an order of magnitude, the former cannot be transmitted by optical fiber, and the latter can be transmitted by optical fiber, which greatly increases the degree of flexibility in processing. In the early days before the launch of fiber lasers on the market, in order to achieve three-dimensional processing, optical joint technology can be used 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.
