When the laser cutting machine is operated correctly, the laser cutting machine can achieve high-speed production, but if the daily operation and maintenance are not proper, it is easy to cause the phenomenon that the laser cutting machine cannot cut through the plate. The laser cutting machine cannot cut through the plate, which will not only affect the processing quality of the workpiece and waste metal materials, but also have a certain impact on the laser cutting equipment. The main reasons why the laser cutting machine cannot cut through the plate are as follows.
Exceeding the limit cutting thickness
We all know that the thickness of the plate cut by the laser cutting machine is related to the laser power. The power of the fiber laser is usually divided into three gears: low, medium and high power, and the laser power is between 6000w-30000w. However, there is a limit cutting thickness value for laser cutting machines with different powers. If the thickness of cutting metal plates exceeds the limit thickness that the equipment can cut, the cutting of plates will be impervious.
Contamination of optical elements of laser head
The laser cutting machine mainly relies on the laser cutting head to operate the cutting process. The optical elements in the laser cutting head mainly include focusing components, protective lenses, etc. Because the laser cutting head is in a poor working environment for a long time, it is easy to leave residues on the surface of the lens. These residues may lead to the decline of the laser power of the equipment, resulting in the impervious cutting of metal workpieces.
Laser power decrease
After using the laser of the fiber laser cutting machine for a long time, the power will gradually decrease with the use of time, which will eventually lead to the decline of cutting capacity, and there will also be cutting imperfectly.
Offset of cutting focus
Setting the cutting focus of laser cutting machine is one of the important factors that affect the cutting quality. When the laser head cutting focus debugging fails to meet the standard, it may lead to incomplete cutting of plates.
Insufficient air pressure of cutting auxiliary gas
During the cutting operation, the auxiliary gas can blow off the cutting residue and keep the cutting section smooth and flat. However, when the auxiliary gas pressure is not reached, the residue is difficult to remove, which will lead to the cutting impervious.
The laser cutting machine cannot cut through the plate, which will not only affect the processing quality of the workpiece and waste metal materials, but also have a certain impact on the laser cutting equipment.
To sum up, the above are the common reasons that affect the laser cutting machine's inability to cut through metal plates. Users can pay more attention to these problems when using the equipment in daily life. In the face of problems in processing, they need to further solve them, so that metal parts can obtain better processing effect and improve processing efficiency through the laser cutting machine.
