With the increasing popularity of metal processing laser cutting machines, more and more users begin to choose to use laser cutting machines to process metal materials of different thicknesses. In the process of laser cutting machines, it is rare that metal plates cannot be cut through. What is the reason for this? Why does laser cutting equipment have the problem of cutting through plates? After reading the following content, you will understand!

When the laser cutting machine is operated correctly, the laser cutting machine can realize high-speed production. However, if the daily operation and maintenance are improper, it is easy to cause the phenomenon that the laser cutting machine cannot cut through the plates. The laser cutting machine can not 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. Laser cutting machine can not cut through the plate mainly because of the following.

Exceeding the limit cutting thickness

As we all know, 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. The laser power is between 6000W and 30000W. However, there is a limit cutting thickness value for laser cutting machines with different powers. If the thickness of the metal plate to be cut exceeds the limit thickness that can be cut by the equipment, the plate will be cut impenetrably.

Laser head optics contamination

The laser cutting machine mainly relies on the laser cutting head to run the cutting process. The optical components 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 residue on the lens surface, which may lead to the reduction of the laser power of the equipment, resulting in the situation that the metal workpiece cannot be cut through.

Laser power drop

After using the laser of the fiber laser cutter for a long time, the power will gradually decrease with the use of time, which will eventually lead to the decline of the cutting ability, and the situation of cutting penetration will also occur.

Offset of cutting focus

Cutting focus setting of laser cutting machine is one of the important factors affecting cutting quality. When the laser head cutting focus debugging fails to meet the standard, it may lead to incomplete plate cutting.

Insufficient cutting auxiliary gas pressure

During the cutting operation, the auxiliary gas can blow off the cutting residue to keep the cutting section smooth and flat. However, when the auxiliary gas pressure cannot reach, it is difficult to remove the residue, which will lead to impermeable cutting.

The laser cutting machine can not 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, and further solve the problems that occur in the processing, so that metal parts can obtain better processing effect and improve processing efficiency through the laser cutting machine.
