Daily use specifications and maintenance instructions of fiber laser cutting machine

With the continuous development of my country’s laser industry, more and more laser equipment appear 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 that is newly developed in the world. It outputs high-energy-density laser beam, which is concentrated 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. Realize automatic cutting by irradiating position, fast 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 current limitations, such as processing material property restrictions and strict processing specifications.

Let me 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 plates and pipe cutting. It is not possible 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-mentioned materials, or the absorption is inappropriate, and the ideal cutting effect cannot be achieved. At present, it is used in The advantages of non-metal cutting are not obvious, and there may be a trend toward this 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 reflectiveness has little to do with the smoothness of the cutting surface of the plate, 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 increase. 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, 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 “friendly to the people” at present, it is necessary to frequently process and maintain the machinery during use, so as to extend the service life of the machinery. , To maximize the efficiency of the equipment.

First of all, you must always check the steel belt. The steel belt plays a very important transmission role in the operation of the laser cutting machine. The tension of the steel belt must be ensured when the equipment is running. Otherwise, once there is a problem in operation, there is a high possibility that people will be injured, and it can even cause death in serious cases. The steel belt seems to be just a small thing, but once something goes wrong, it will seriously affect production safety. Secondly, because 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 pressure of the machine. The parts are spotless, and the normal operation of the parts is better maintained. In addition, it is necessary to lubricate the racks, rails and many parts of the cutting machine from time to time, so as to stabilize the accuracy of the gears during operation. As a result, the operation of the machine is always in the normal running track, and the precision of the cut products is of course higher.

While doing the daily maintenance of the equipment, strict inspections must be carried out when purchasing the equipment and its parts, so as to fundamentally ensure the normal production of the machinery. At the same time, if any parts are found to be damaged during the use of the machine, they must be replaced in time. This not only protects the machine itself, but also ensures that the laser cutting machine always maintains an ideal cutting effect.
