Fiber laser cutting machine is a laser cutting machine using fiber laser generator as light source. Optical fiber laser is a newly developed new type of optical fiber laser in the world, which outputs high energy density laser beam and gathers on the surface of the workpiece, which makes the workpiece melt and gasify the area illuminated by the ultrafine focus spot instantaneously.
However, fiber laser cutting machine is not omnipotent, no matter how perfect the equipment will also have its shortcomings, we should not only see its superior processing performance, but also pay attention to its own current limitations, such as processing material attribute restrictions, strict processing specifications, and so on.
First of all, the fiber laser cutting machine processing category. Before the fiber laser cutting machine mainly belongs to the metal laser cutting machine processing category, so the main cutting metal, such as stainless steel, carbon steel, alloy steel, silicon steel, spring steel, aluminum, aluminum alloy, galvanized plate, acid washing plate, copper, silver, gold, titanium and other metal plate and pipe cutting. But with the development of technology, the technology of non-metallic cutting in plastics, composites and plexiglass has also matured.
Secondly, fiber laser cutting machine does not recommend long-term cutting aluminum, copper and other rare metal materials, although the processing of these materials are really good, but because these materials belong to high-reflective materials (note: high-reflective and plate cutting surface smoothness is not related, mainly because the wavelength of the laser is not within the ideal absorption range of these materials, absorption effect is not good, most of the energy is reflected back, easy to damage the protection lens in front of the laser head), the long-term action on these materials may affect the service life resulting in the subsequent processing effect is not good, will also increase the use of consumables. Finally, the fiber laser cutter is based on its high power Small difference, cutting thickness also changes, the greater the power, the greater the cutting thickness; the thinner the metal material, the faster the cutting speed, the fiber laser cutting machine for thin plate cutting advantage is very obvious.
