What is the reason for the power drop of metal laser cutting machine

The role of metal laser cutting machine in the processing field is very huge, but the power of the metal laser cutting machine may drop after a period of use. But why is there a problem of power drop? The reason has always been of more concern to everyone. Let's take a look together below.   When the power of the metal laser cutting machine drops, first observe the color of the generator glass tube. If it is found that it is pink even at high power, it can be inferred that the generator is malfunctioning. At this time, we should check the generator for air leakage and burn the thermal paper, and record the inspection results. The generator air leakage inspection is a self-inspection of the machine tool air leakage under the operation of the operator. Under normal circumstances, the air leakage cannot be greater than 5 mbr/hour. The result is that the air leakage reaches 54 mbr/hour to determine that the generator has leaked. When doing the thermal paper burning experiment, if the burned hole is not round and not burned through, it can be preliminarily judged that the power of the machine has been reduced and the laser transmission angle mirror has shifted.   If there are cracks in the glass tube of the laser generator, try to seal the cracks with glass glue and check the generator leakage. If the leakage per hour is less than 5mBar, it meets the requirements. If the color of the generator glass tube of the part sealed with glass glue turns dark red, it can be judged that the cutting power is very low, which proves that the method is not advisable.   Do the thermal paper burning experiment again, and clean and maintain the 5 reflectors of the machine. Use special tools to spend a lot of time on beam alignment. After the inspection, if the color of the laser generator glass tube is normal, use a special tool to detect that the laser power is slightly lower than the normal level. Then the B-axis lens was replaced, and the test power was completely normal.   Generally speaking, problems such as high air humidity, large difference between the air pressure inside the glass tube and the outside air pressure of the glass tube, aging or defects of the B-axis will affect the utility of the metal laser cutting machine to a certain extent.
