What are the reasons for the power drop when using a laser cutting machine

Many customers find that the power of the laser cutting machine has decreased during the process of using the laser cutting machine, so they hope to understand the reason for the decrease in the power of the laser cutting machine in order to improve it. Below we will give you a breakdown of the reasons for the power drop of the laser cutting machine.   When you use the laser cutting machine, if you find that its power has dropped, first observe the color of the generator glass tube. If you find 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 leak inspection is a self-inspection of the machine's 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 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 is a crack in the glass tube of the laser generator, you can try to seal the crack 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.   Wuhan Gaoneng Laser Equipment Manufacturing Co., Ltd. is a high-tech enterprise integrating Ru0026D, production and sales of professional laser complete sets of equipment.
