Laser cutting machine widely used in the production of modern life, he can be divided into three types, simply introduce the advantages of the three kinds of laser cutting machine:
YAG solid laser cutting machine has the features of low price and good stability, but low energy efficiency < 3%, most of the current product output power under 600 w, due to the smaller output energy of the plate is mainly used in perforating and spot welding and cutting. Its green laser beam can be used in the case of a pulse or a continuous wave, a short wavelength, concentrated sex is suitable for precision machining especially under the pulse hole machining is the most effective, and can also be used for cutting, welding and printing etc.
Optical fiber laser cutting machine because it can be through the optical fiber transmission, flexible degree of unprecedented increase, point of failure, less maintenance convenience, speed fast, so in cutting thin plate within 4 mm fiber cutting machine has a great advantage, but under the influence of solid laser wavelength it poor quality when cutting thick plate. The wavelength of the fiber laser laser cutting machine is 1.06 um, not easily absorbed by nonmetal, so can’t cutting non-metallic materials. Optical fiber laser photoelectric conversion rate as high as 25% above, in electricity consumption, form a complete set of the cooling system has the advantage of optical fiber laser is quite obvious.
CO2 laser cutting machine, can stable cutting carbon steel within 20 mm, less than 10 mm stainless steel, aluminum alloy under 8 mm. CO2 laser wavelength is 10.6 um, more easily absorbed by nonmetal, can high quality cutting wood, acrylic, non-metallic materials such as PP, organic glass, but the CO2 laser photoelectric conversion rate is only about 10%.
