When using the stainless steel optical fiber laser cutting machine, workers will always encounter problems of one kind or another. The most common problem is cutting materials, which makes workers worried. This kind of problem usually occurs because the air pressure of the laser cutting machine is not adjusted properly. Here's how to learn about the stainless steel laser cutting machine!

In the process of laser cutting, the pressure of auxiliary gas has a great influence on the cutting results. The auxiliary gas must have enough pressure to completely remove the waste residue generated by cutting. Generally, when cutting a thicker workpiece, the air pressure should be reduced a little, and the residue stuck to the workpiece will damage the cutting edge.

Increasing the gas pressure can advance the cutting speed, but after reaching a maximum value, increasing the gas pressure will cause the cutting speed to decrease. Under high auxiliary gas pressure, the reason why the cutting speed of the laser cutting machine decreases can be attributed to the enhancement of the cooling effect of the high air flow speed and the hanging area, and may also be the interference of the intermittent shock wave in the air flow to the cooling of the laser area. The uneven pressure and temperature in the air flow will cause the change of the air flow field density. Such density gradient will change the refractive index in the field, which will interfere with the focusing of beam energy and cause refocusing or beam divergence. This interference will affect the melting efficiency, and sometimes may change the mode structure, leading to a decline in cutting quality, if the beam is too divergent. The light spot is too large, which may even lead to serious consequences of not being able to cut effectively.

The laser beam is tapered, so the slit is also tapered. In this case, the stainless steel with a thickness of 0.4MM will be much smaller than the slit with a thickness of 3MM. Therefore, the shape of the laser beam depends on a major factor affecting the cutting accuracy of the metal laser cutting machine. In this tapered laser beam condition, the greater the thickness of the workpiece, the lower the accuracy, and therefore the larger the kerf. Even for the same material, if the composition of the material is different, the cutting accuracy will also be different. Therefore, the workpiece material has a certain impact on the laser cutting accuracy.

If the accuracy of the worktable is uneven or other reasons will also lead to high-precision laser cutting effect.

Optical fiber laser cutting is the reason for continuous cutting of metal plates. Today, Longtai Laser answers for you. The key word of this is gas. As we all know, when using the optical fiber laser cutting machine to cut, a certain amount of auxiliary gas is required. At this time, the auxiliary gas must have enough pressure to completely remove the waste residue generated by cutting. Generally, when cutting a thicker workpiece, the air pressure should be reduced a little, and the residue stuck to the workpiece will damage the cutting edge. When the gas pressure is increased, the cutting speed can be advanced, but after reaching a maximum value, increasing the gas pressure will cause the cutting speed to decrease. This interference will affect the melting efficiency, and sometimes may change the mode structure, leading to a decline in cutting quality, if the beam is too divergent. The light spot is too large, which may even lead to serious consequences of not being able to cut effectively.
