The optical fiber laser cutting machine is a laser cutting machine that uses the optical fiber laser generator as the light source. The laser beam with high energy density is output and gathered on the surface of the workpiece, which makes the workpiece melt instantaneously and vaporize the area irradiated by the ultra-fine focus.
However, optical fiber laser cutting machine is not omnipotent. No matter how perfect the equipment is, it will also have its shortcomings. We should not only see its superior processing performance, but also pay attention to its current limitations, such as the property limitation of processing materials, strict requirements, etc. Processing specifications, etc.
First is the processing category of optical fiber laser cutting machine. The previous optical fiber laser cutting machine mainly belongs to the processing category of metal laser cutting machine, so it mainly cuts metals, such as stainless steel, carbon steel, alloy steel, silicon steel, spring steel, aluminum, aluminum alloy, galvanized plate, pickled plate, copper, silver, gold, titanium and other metal plates and pipes. However, with the development of technology, the non-metallic cutting technology of plastics, composite materials and plexiglass has also matured.
Secondly, optical fiber laser cutting machine is not recommended to cut aluminum, copper and other rare metal materials for a long time. Although the processing of these materials is really good, these materials belong to high reflective materials (Note: the smoothness of the cutting surface of the high reflective plate is irrelevant, mainly because the wavelength of the laser is not within the ideal absorption range of these materials, the absorption effect is not good, and most of the energy is reflected back, which is easy to damage the protective lens in front of the laser), The long-term effect on these materials may affect the service life, resulting in poor subsequent processing results, and will also increase the use of consumables. Finally, the fiber laser cutting machine is based on the small difference of its high power, and the cutting thickness will also change. The greater the power, the greater the cutting thickness; The thinner the metal material is, the faster the cutting speed is. The advantages of optical fiber laser cutting machine for thin plate cutting are very obvious.
