The metal fiber laser cutting machine must use maintenance gas during processing. Air is of course a simple and economical maintenance gas. The function of the air compressor is to compress a part of the air with high-purity oxygen and high-purity nitrogen to form the cutting gas. A part of the cutting head is used as a power source to supply the cylinder of the clamping table, and then a part is used to stop the purge and dust removal of the optical path system. After the compressed air discharged from the air enters the air control cabinet through the air storage tank and the dryer, After a sophisticated disposal system, it becomes clean and boring gas, which is finally divided into three channels, which are respectively used as cutting gas, cylinder power source and light path positive pressure dust removal gas to maintain the normal operation of the metal fiber laser cutting machine, so the air compressor It is indispensable for every laser cutting equipment, and it is also very important for metal fiber laser cutting machine.

The air is directly provided by the air compressor, so the price is very cheap compared with other gases. Although the air contains about 20% oxygen, the cutting efficiency is far less than that of oxygen, and cutting can be similar to nitrogen. The cut surface will show a small amount of oxide film, but it can be used as a measure to prevent the coating layer from falling apart. The end face of the incision is yellow.
The main applicable materials are aluminum, aluminum alloy, stainless copper, brass, electroplated steel plate, etc.


Some factors that affect the life of a metal fiber laser cutting machine. Regarding the metal fiber laser cutting machine, it is the pump source and crystal inside that affect the life of the metal fiber laser cutting machine, which is actually the life of the lamp. Generally speaking, the life of the standard lamp and the life of the crystal are equal. When the energy drops, the processing performance of the metal fiber laser cutting machine will be greatly reduced, so the only way to deal with it is to change the pump source and crystal.

When the metal fiber laser cutting machine stops cutting the material, a large amount of gas and splashes will be released from the work surface, and these gas and splashes will damage the lens. When contaminants fall on the surface of the lens, it will absorb energy from the laser beam, causing a thermal lens effect. If the lens has not yet constituted thermal stress, the operator can remove it and clean it.
The power of the metal fiber laser cutting machine drops suddenly, and the glass tube may break. There are watermarks on the wall of the broken glass tube. The power of the air conditioner and the air dryer can be increased to reduce the air humidity; high temperature with high humidity may also cause the glass to break. There is no dirt and residual traces left on the surface of the mirror; blow dry with dry air; if necessary, roll the lens paper moistened with a few drops of acetone into a rod, and quietly scrub the surface of the lens to remove heavy drops of dirt.
Many customers start to put the metal metal fiber laser cutting machine into operation after the assembly is completed, and the burrs are very obvious in the application. Why?
1. First check whether there is a problem with the laser output and whether the spot is very round (the circle indicates that the lateral dispersion of the laser energy is average, and the energy distribution of the light spot formed after the lens is more even. The cutting quality is only it is good)
2. Check whether the lens in the laser transmission process is dirty, whether the lens is dirty, whether the lens has small cracks that are not easy to find with the naked eye, these will affect the transmission of laser power.
At the end of the above two inspections, we can confirm whether the laser itself is good, and only then will the adjustment of the process parameters. The burrs produced by the tube metal fiber laser cutting machine cutting stainless steel have certain hardness, which is difficult to remove. It has to be time-consuming and affects the aesthetics of the workpiece. It is best to deal with it from the source. The purity of the gas should be high. If you can change to a better quality gas supplier, the purity of the gas is very important. It is best not to use steel cylinder gas, because after two fillings, the purity is not good, and the gas is wasteful. The next step is to adjust the cutting parameters to the best. The air pressure, flow, focal length and cutting speed must be adjusted many times. The parameters provided by the machine cannot be used to cut delicate workpieces. Equipment + gas + parameters, adjusted to the best, the cut workpiece is free of burrs.
