With the continuous development of China's laser industry, more and more laser equipment appears in people's life and work, and the appearance of fiber laser makes the application of laser equipment more diversified, so the laser cutting machine has gained new "life".

Fiber laser cutting machine is a laser cutting machine using fiber laser generator as light source. Fiber laser is a new type of fiber laser developed internationally that outputs high energy density laser beams and gathers them on the surface of the workpiece to instantly melt and vaporize the area on the workpiece illuminated by the ultra-fine focus spot. Automatic cutting is realized by moving the spot irradiation position through the numerical control mechanical system, with fast speed and high accuracy.

However, the optical fiber laser cutting machine is not omnipotent. While we see its superior processing performance, we should also pay attention to its own limitations, such as the material property restrictions and strict processing specifications.

First, let's talk about the processing category of optical fiber laser cutting machine. Optical fiber laser cutting machine belongs to the processing category of metal laser cutting machine, so it can only cut metals, such as stainless steel, carbon steel, alloy steel, silicon steel, spring steel, aluminum, aluminum alloy, galvanized plate, aluminum zinc plate, pickling plate, copper, silver, gold, titanium and other metal plates and pipe cutting. It is not possible to cut non-metal materials such as cloth, leather and stone. The reason is simple. The wavelength range of the optical fiber laser cutting machine is not within the absorption range of the above materials, or the absorption is inappropriate, which cannot achieve the ideal cutting effect. At present, the advantages of applying it to non-metal cutting are not obvious, and there may be a trend in this regard in the future.

Secondly, the optical fiber laser cutter is not recommended to cut aluminum, copper and other rare metal materials for a long time, because these materials are high reflective materials (Note: high reflective materials have little to do with the smoothness of the cutting surface of the plate, mainly because the wavelength of the laser is not within the ideal absorption range of these materials, 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), and the long-term use effect is not good, It will also increase the use of consumables. Finally, the cutting thickness of the optical fiber laser cutting machine changes according to its power. 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.

Now let's talk about the processing specifications of the optical fiber laser cutting machine. Because the current price of the optical fiber laser cutting machine in China is not very "user-friendly", the machine needs to be frequently processed and maintained during the use process, so as to extend the service life of the machine and maximize the working efficiency of the equipment.

First of all, always check the steel strip. The steel strip plays a very important role in the operation of the laser cutting machine. Make sure that the steel strip is tight when the equipment is running. Otherwise, once there is a problem in the operation, it is very likely to hurt people and even cause death. The steel belt looks like a small thing, but once it goes wrong, it will seriously affect the safety production. Secondly, because the laser cutting machine will directly vaporize the metal surface when cutting, so a lot of dust will often be generated on the surface and inside of the cutting machine. We should often use vacuum cleaners to suck out the dust, so as to ensure that the internal parts of the machine are spotless and better maintain the normal operation between parts. In addition, it is also necessary to lubricate the rack, guide rail and many cutting machine parts irregularly, so as to stabilize the accuracy of gear engagement during operation. The machine is always in the normal running track, and the precision of the cut products is certainly higher.

While doing a good job in daily maintenance of equipment, strict inspection must be carried out when purchasing equipment and its parts, which can fundamentally ensure the normal production of machinery. At the same time, if any part is damaged during the use of the machine, it must be replaced in time, which is not only a protection for the machine itself, but also can ensure that the laser cutting machine always maintains an ideal cutting effect.
