With the continuous development of the laser industry in our country, more and more laser devices are appearing in people's lives and work. The emergence of fiber lasers has made the application of laser devices more diversified, and laser cutting machines have also obtained New "life."
The fiber laser cutting machine is a laser cutting machine using a fiber laser generator as a light source. Fiber laser is a new type of fiber laser that is newly developed in the world. It outputs a laser beam with high energy density and collects on the surface of the workpiece. It instantly melts and vaporizes the area on the workpiece that is illuminated by the ultra-fine focus spot, and moves the spot through a numerically controlled mechanical system. Irradiation position and automatic cutting, high speed and high precision.
However, the fiber laser cutting machine is not a panacea. We must pay attention to its own limitations at the same time when we see its superior processing performance, such as the limitation of the material properties of processing, strict processing specification requirements, and so on.
Let's talk about the processing area 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 steel sheet, pickling plate , copper, silver, gold, titanium and other metal sheet and pipe cutting. Can not cut cloth, leather, stone and other non-metal, the reason is very simple, the wavelength range of fiber laser cutting machine is not within the absorption range of the above materials, or the absorption is not suitable, can not achieve the ideal cutting effect. At present, the application The advantages of non-metallic cutting are not obvious, and there may be trends in this direction in the future.
Secondly, fiber laser cutting machines do not recommend the long-term cutting of rare metals such as aluminum and copper because these materials are highly reflective materials. (Note: High reflectivity is not related to the smoothness of the cut surface of the plate, mainly because the wavelength of the laser is not Within the ideal absorption range of the material, the absorption effect is not good, most of the energy is reflected back, and the protective lens in front of the laser head is easily damaged. The long-term use effect is not good, and the consumption of consumables is also increased. Finally, according to the different power levels of the fiber laser cutting machine, the cutting thickness also changes. The greater the power, the greater the thickness of the cutting. The thinner the metal material, the faster the cutting speed, and the advantage of the fiber laser cutting machine for thin plate cutting is obvious.
Let's talk about the fiber laser cutting machine processing specifications, because the current price of fiber laser cutting machine in the country is not very "close to the people", so in the use of the process often need to machine processing and maintenance, so as to extend the service life of the machine To maximize the efficiency of the equipment.
First of all, we must always check the steel strip. The steel strip plays a very important role in the operation of the laser cutting machine. We must ensure the tension of the strip during the operation of the equipment. Otherwise, if there is a problem in the operation, there is a great possibility that it will injure people, and it will seriously lead to the death of the people. The steel belt may seem like a small thing, but once it does, it will seriously affect safety production. Secondly, because the laser cutting machine directly vaporizes the metal surface during 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 these dusts so as to ensure the inside of the machine. The components are spotless and better maintain normal operation between components. In addition, it is also necessary to lubricate the racks, guide rails, and parts of many cutting machines from time to time, which can stabilize the accuracy of gear engagement during operation. The operation of the machine is always in the normal operation track, and the accuracy of the cut product is certainly higher.
While carrying out routine maintenance of the equipment, it is also necessary to conduct strict inspections when purchasing equipment and its parts and components. This can fundamentally ensure the normal production of machinery. At the same time, if any parts are damaged during the use of the machine, they must be replaced in time. This is not only a protection for the machine itself, but also ensures that the laser cutting machine always maintains an ideal cutting effect.
