Fiber laser cutting machine is a laser cutting machine that uses fiber laser generator as the light source. Fiber laser is a new type of fiber laser developed in the world, which outputs high energy density laser beam and gathers on the surface of the workpiece to melt and vaporize the area irradiated by the ultra-fine focus spot on the workpiece instantly. The automatic cutting is realized by moving the spot irradiation position through the numerical control mechanical system, with high speed and precision.

However, the fiber laser cutting machine is not universal. When we see its superior processing performance, we should also pay attention to its current limitations, such as processing material property restrictions, strict processing specification requirements, etc.

First, let's talk about the processing category of fiber laser cutting machine. Optical 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 plate, aluminum-zinc plate, pickling plate, copper, silver, gold, titanium and other metal plates and pipes. Non-metallic materials such as cloth, leather and stone cannot be cut. 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 appropriate, and the ideal cutting effect cannot be achieved. At present, the advantages of applying it to non-metal cutting are not obvious, and there may be a trend to develop in this area in the future.

Secondly, optical fiber laser cutting machine 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 has little to do with the smoothness of the cutting surface of the plate, mainly because the laser wavelength is not within the ideal absorption range of these materials, and the absorption effect is not good. Most of the energy is reflected back, which is easy to damage the protective lens in front of the laser head), the long-term use effect is not good, and will also increase the use of consumables. Finally, the cutting thickness of the 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 fiber laser cutting machine has obvious advantages for sheet cutting.

Let's talk about the processing specifications of the fiber laser cutting machine. Because the current price of the fiber laser cutting machine in China is not very "people-friendly", it is necessary to process and maintain the machine frequently in the process of use, so as to extend the service life of the machine and greatly improve the working efficiency of the equipment.

First of all, always check the steel belt. The steel belt plays a very important transmission role in the operation of the laser cutting machine, and ensure the tension of the steel belt during the operation of the equipment. Otherwise, once there is a problem in the operation, there is a great possibility that people will be injured or even killed. The steel belt seems to be a small thing, but once it goes wrong, it will seriously affect the safety of production.

Secondly, because the laser cutting machine will directly vaporize 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 dust, so as to ensure that the parts inside the machine are spotless and better maintain the normal operation of the parts.

In addition, it is also necessary to lubricate the rack, guide rail and many cutting machine parts from time to time, so as to stabilize the accuracy of gear engagement during operation. Make the machine always in the normal operation track, and the precision of the cut product is of course higher.

While doing a good job in the daily maintenance of the equipment, when purchasing the equipment and its parts, we must also carry out strict inspection, which can fundamentally ensure the normal production of the machinery. At the same time, if any parts are damaged during the use of the machine, they 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.
