In recent years, we have seen the rapid development of science and technology in our great motherland. This made me feel extremely proud for me as a Chinese. With the advancement of technology and the progress of people, we will join the Chinese cutting machine trading network to make progress together. Join the hotline, we look forward to your call.

In many modern industries we see the use of many laser cutting machines, but we can't guarantee that we can get the ideal cutting quality. Each cutting parameter is limited to a narrow range. For now, it can only be achieved through continuous The experiment can get more reasonable parameters, this method is very costly to verify the quality of the Aurora cutting machine, and there is no way to respond to factors in the cutting process.
High-quality laser cutting mainly refers to the fact that there is no cutting defect and the cutting surface roughness value is small. Therefore, in the ancient city where the inspection test is performed, the target should be able to identify the cutting defect and detect the information that reflects the roughness of the cutting surface, in which the rough surface is obtained. The information is most important and the difficulty is also the greatest.
The most important research result of the rough surface detection work is to find that the frequency of the pulsation frequency of the cutting front optical radiation signal is equal to the frequency of the cutting stripe on the cutting surface, and the frequency of the cutting stripe is closely related to the roughness. We use the photoelectricity. Tube detection of radiation signals can be related to the cutting surface roughness. This method of detecting roughness is relatively simple, but there are many deficiencies:
After further research, we have shown that the agreement between the frequency of the cutting front optical radiation signal and the frequency of the fringe on the cutting surface is limited to a range of small cutting speeds. When the cutting speed is greater than a certain cutting speed, the main frequency of the signal disappears. Train any information related to cutting stripe.
Therefore, the metal cutting only needs to rely on the front edge of the light radiation signal is more limited, it is difficult to obtain effective and valuable cutting machine rough information at normal cutting speed, especially the edge of the edge of the roughness information. Only after confirming the roughness condition can we confirm the quality of the laser cutting machine.
