What is the reason why the fiber laser cutting machine cannot cut through the workpiece?

As the application of fiber laser cutting machine becomes more and more extensive, there are often some problems in the cutting process, and the situation that the fiber laser cutting machine does not cut through the sheet is very troublesome. What is the cause? oreelaser will analyze it for everyone.

1. The power of the laser drops

The laser power of the fiber laser cutting machine will gradually decrease due to long-term use. The lower the laser power, the more likely it is that the sheet cannot be cut through.

2. Optical component contamination

Optical components include collective mirrors, reflecting mirrors, etc., because they have been in a poor working environment for a long time, residues are easily left on the surface of such lenses, which reduces the laser power of the equipment, resulting in impenetrable cutting.

3. Unqualified equipment spot debugging

The light spot of the fiber laser cutting machine is a very important element that affects the cutting quality. When the light spot debugging does not meet the standard, the cutting will not achieve.

4. The cutting speed of the laser cutting machine is too fast

If the cutting speed is too fast, the missing cut will inevitably occur, and it will also lead to incomplete cutting.

5. The thickness of the processed plate exceeds the equipment limit

There is a limit cutting thickness for fiber laser cutting with different powers. If the limit thickness is exceeded, the equipment will not cut through the plate.

6. The auxiliary gas pressure is not high

The fiber laser cutting machine must have auxiliary gas when cutting, and the auxiliary gas must be under a certain pressure to completely remove the waste generated during cutting. When the air pressure does not reach a certain level, the residue is difficult to remove, which will cause cutting impenetrable situation. Increasing the air pressure can increase the cutting speed, but after reaching the limit, continuing to increase the air pressure will decrease the cutting speed.

7. The choice of laser head nozzle does not match the thickness of the processed sheet
