Daily use specification and maintenance method of fiber laser cutting machine
With the continuous development of my country's laser industry, more and more laser equipment appears in people's lives and work, and the emergence of fiber lasers has made the application of laser equipment more diversified, and laser cutting machines have also gained new "life".
Fiber laser cutting machine is a laser cutting machine that uses a fiber laser generator as a light source. Fiber laser is a new type of fiber laser developed in the world. It outputs a laser beam with high energy density and gathers it on the surface of the workpiece, so that the area irradiated by the ultra-fine focus spot on the workpiece is instantly melted and vaporized, and the spot is moved by the numerical control mechanical system. The automatic cutting is realized according to the irradiation position, with high speed and high precision.
However, the fiber laser cutting machine is not omnipotent. While seeing its superior processing performance, we must also pay attention to its own limitations, such as the limitations of material properties for processing and strict processing specifications.
First, let's talk about the processing category of fiber laser cutting machine. Fiber laser cutting machine belongs to the processing category of metal laser cutting machine, so it can only cut metal, such as stainless steel, carbon steel, alloy steel, silicon steel, spring steel, aluminum, aluminum alloy, galvanized sheet, galvanized sheet, pickling sheet , copper, silver, gold, titanium and other metal sheet and pipe cutting. It is impossible to cut non-metals such as cloth, leather, stone, etc. The reason is very simple. The wavelength range of the fiber laser cutting machine is not within the absorption range of the above materials, or the absorption is not suitable, and the ideal cutting effect cannot be achieved. The advantages of non-metal cutting are not very obvious, and there may be a trend in this direction in the future.
Secondly, fiber laser cutting machine is not recommended for long-term cutting of rare metal materials such as aluminum and copper, because these materials are highly reflective materials (Note: high reflection has little to do with the smoothness of the cutting surface of the sheet, mainly because the wavelength of the laser is not in these Within the ideal absorption range of the material, the absorption effect is not good, most of the energy is reflected back, and it is easy to damage the protective lens in front of the laser head), the long-term use effect is not good, and the consumption of consumables will be increased. Finally, the cutting thickness of the fiber laser cutting machine changes according to its power. The higher the power, the greater the cutting thickness; the thinner the metal material, the faster the cutting speed. The fiber laser cutting machine has obvious advantages for thin plate cutting.
Let's talk about the processing specifications of fiber laser cutting machines. Since the price of fiber laser cutting machines in China is not very "close to the people", it is necessary to process and maintain the machinery frequently during the use process, so as to prolong the service life of the machinery. , to maximize the efficiency of the equipment.
First of all, the steel belt must be checked frequently. The steel belt plays a very important transmission role in the operation of the laser cutting machine, and the tension of the steel belt must be ensured during the operation of the equipment. Otherwise, once there is a problem in operation, there is a high possibility that people will be injured, and it may even lead to death. The steel belt seems to be just a small thing, but once there is a problem, it will seriously affect the safety of production. Secondly, since the laser cutting machine will directly vaporize the metal surface when cutting, a lot of dust will often be generated on the surface and inside of the cutting machine. We should often use a vacuum cleaner to suck out the dust, so as to ensure the internal dust of the machine. The parts are spotlessly clean, which better maintains the normal operation of the parts. In addition, it is also necessary to lubricate the racks, guide rails and many parts of the cutting machine from time to time, which can stabilize the accuracy of the gear engagement during operation. The operation of the machine is always in the normal running track, and the precision of the cut product is of course higher.
