Laser cutting machine in the process of cutting, intelligent operating system control equipment in accordance with the instructions to run, laser gathered laser energy output to laser cutting head, laser cutting head will be issued by the laser beam of energy, focusing the formation of a laser beam to be cut the surface of the workpiece, so that it melts or burns, coupled with cutting gas, will blow away the slag, cutting head in the workpiece surface movement, the formation of slit, The process of separating work pieces.
Laser cutting head directly affects the processing performance and quality of laser cutting machine, because the laser cutting head cost is expensive, in the use of laser cutting machine for processing, in order to protect the laser cutting head internal optical path and core components, especially the collimation and focusing mirror and other expensive parts, will give the laser cutting head installation protective lenses, block cutting dust and splash.
If the protective lens often burns out frequently, we need to pay attention to this situation, judge what causes the frequency burning phenomenon of the protective lens, whether it is the quality problem of the protective lens or the peacetime maintenance problem. Next Xiaobian will introduce several reasons for the frequency of laser head protection mirror burning:
1. The blowing delay is too small, resulting in the laser coming out before the gas. The blowing parameter delay within the global parameters is too small or zero. Increase the blowing delay, pay attention to adjust the focal length when cutting, and the thickness of the plate to be cut, the stability of the air pressure have a certain impact on the lens.
2, no perforating process is set, it is recommended to adjust more than 1 mm to increase the perforating process. The number of perforations in the corresponding time should be kept in mind, because its output frequency is higher because the perforation sputtering damage lens, so before perforation, set the time, generally 500hz continuous wave, will not exceed 150.
3. Internal pollution of gas pipeline leads to cutting pollution. It is recommended to clean up the gas pipe in time.
4. For the problem of protective lenses, it is recommended to use the original protective lenses.
5, internal protection mirror pollution. Remember to dust when the work is finished every day, dust should be careful, and careful when cleaning, because the lens is afraid of falling, afraid of touching, even when replacing the new lens should be done first dust.
In addition, the cleaning degree of the protective mirror is also the key factor that determines the lasting use of the protective lens. Whether the protective lens is clean or not directly affects the processing performance and quality of the output of the laser cutting machine. If the lens is dirty, it will not only affect the cutting effect and efficiency, but also further cause the internal parts of the cutting head and the output head of the laser to burn. Therefore, the first need to use good material, high light transmittance, small thermal expansion coefficient of the protective mirror, when the lens is dirty in the process of processing, need to clean or replace. While checking the lenses, don’t forget to check the normal operation of the air compressor dryer every day.
The above content is the cause of the protection mirror burning and operation guidance suggestions, I hope to help you, want to know more information about laser cutting machine please pay attention to Pengwo laser or background message, Pengwo laser wholeheartedly welcome your visit!
