With the continuous development of laser industry in China, more and more laser devices appear in people's life and work. The emergence of fiber lasers has made the application of laser devices more diversified, and laser cutting machine has also gained a new "life".
A fiber laser cutting machine is a laser cutting machine using a fiber laser generator as a light source. Fiber laser is a laser beam as a new type of fiber laser output with high energy density on the new international development, and gathered on the surface of the work piece, so that the workpiece is fine focal spot area irradiated by the instant melting and evaporation, the numerical control mechanical system of mobile laser spot location and automatic cutting, high speed, high precision.
However, fiber laser cutting machine is not universal. When we see its superior processing performance, we must also pay attention to its own existing limitations, such as material property limitations and strict processing specifications.
First of all, talk about the processing category of the optical fiber laser cutting machine. Processing category of metal laser cutting machine laser cutting machine, so only cutting metal, such as stainless steel, carbon steel, alloy steel, silicon steel, spring steel, aluminum, Aluminum Alloy, galvanized plate, galvanized plate, pickling plate, copper, silver, gold, titanium and other metal plate and pipe cutting. Not cutting cloth, leather, stone and other non metals, the reason is very simple, fiber laser cutting machine of the wavelength range is not within the range of the absorption material, or absorption is not appropriate, to reach the ideal cutting effect, at present, applied to the metal cutting advantage is not obvious, in May to go this way the development trend of the future.
Secondly, do not recommend long-term cut aluminum, copper and other rare metal materials of fiber laser cutting machine, because these materials are highly reflective materials (Note: cutting with high reflective plate surface smooth degree of little, mainly due to the wavelength of the laser is not in these materials ideal absorption range, the absorption effect is not good, most the energy to be reflected back, protection of the lens is easy to damage the laser head in front), long-term effect is not good, will increase the amount of use of consumables. Finally, according to the different power of the fiber laser cutting machine, the cutting thickness will also change. The larger the power, the greater the cutting thickness. The thinner the metal material and the faster the cutting speed, the advantage of fiber laser cutting machine for thin plate cutting is very obvious.
Come to talk about the processing specification of optical fiber laser cutting machine, the fiber laser cutting machine in the domestic price is not very close to the people, so the need for regular processing and maintenance of equipment in the process of using, so as to prolong the service life of machinery, equipment to improve the work efficiency of the process.
First of all, we must check the steel strip regularly. The steel belt plays a very important role in the operation of laser cutting machine. When the equipment is running, it must ensure the tension of the steel belt. Otherwise, if there is a problem in the operation, there is a great possibility that it will hurt the person, and it can cause the death of the people seriously. Steel strip seems to be just a small thing, but once a problem has a serious problem, it will seriously affect the safety of production. Secondly, because at the time of cutting will direct the vaporization of metal surface laser cutting machine, cutting machine in the surface and inside will often produce a lot of dust, we should often use the dust suction vacuum cleaner, so as to ensure the internal mechanical parts between the spotless, normal operation between parts to maintain better. Besides, it is necessary to lubricate the parts of rack, guide rail and many cutting machines irregularly, so that the accuracy of gear alignment can be stabilized. The operation of the machine is always in the normal running track, and the precision of the cut out of the product is of course higher.
