In the metal processing industry, which plays a large role in industrial manufacturing systems, many metal materials can be cut without deformation regardless of their hardness. Of course, for materials with high reflectivity, such as gold, silver, copper and aluminum alloys, they are also good heat conductors, so it is difficult or even impossible for laser cutting machines to cut them. Ultra-high power fiber laser machine technology has clear and huge advantages.
Ⅰ.Features of Ultra-high Power Fiber Laser Cutting Machine
1. Signal transmission
Signal transmission takes the form of electricity-optical-electricity, and the light-emitting part and the light-receiving part do not contact, which can avoid possible feedback and interference from the output end to the input end;
2. Strong ability to suppress noise interference;
3. Durability, high reliability and fast speed
It has the advantages of durability, high reliability and fast speed. The response time is generally within a few seconds. The response time of high-speed photoelectric couplers is sometimes even less than 10ns. Therefore, when designing the system circuit of ultra-high-power fiber laser machine, attention should be paid to the input Isolation when the signal circuit is connected to the microcontroller. Here, using photoelectric coupling is the most common method.
Ⅱ.Adverse Consequences Caused by Improper Operation
However, as a high-tech equipment, if you want to use ultra-high-power fiber laser cutting machine to achieve ideal cutting and processing effects, you must also master its processing technical parameters and operating procedures. Especially during the cutting process of metal laser cutting machine, it is necessary to choose the appropriate cutting speed, otherwise it may cause several bad cutting results, mainly as follows:
1.Laser cutting speed is too fast
When the laser cutting speed is too fast, it will cause the following undesirable results: unable to cut, sparks spray out randomly; causing diagonal lines on the cutting surface, and melt stains on the lower half; causing the entire section to be thicker, but without melt stains. ;
2.Laser cutting speed is too slow
On the contrary, when the laser cutting speed is too slow, it will cause: over-melting and rough cutting surface. The slit widens and melts completely at the sharp corners. Affect cutting efficiency.
Ⅲ.Judging Cutting Speed from Cutting Sparks
In order to make the ultra-high-power fiber laser cutting machine equipment better perform its cutting function, you can judge whether the feed speed is appropriate from the cutting sparks of the laser equipment:
1. If the sparks spread from top to bottom, it indicates that the cutting speed is appropriate;
2. If the spark tilts backward, it indicates that the feed speed is too fast;
3. If the sparks do not spread and are few and condensed together, it means that the speed is too slow.
Ⅳ.AdvantageS
Laser cutting technology has incomparable advantages over other traditional cutting methods. The laser cutting machine not only has the main characteristics of narrow cutting slit and small deformation of the workpiece, but also has the characteristics of fast speed, high efficiency, low cost, safe operation and stable performance.
Ⅴ.Application Areas
In recent years, with the rapid improvement and development of ultra-high-power lasers, their application in industry has evolved from being initially used only for processing small or fine structures to being widely used for processing large structural parts. It has become more and more popular among people. It is paid attention to and recognized and widely used in industrial fields such as machinery manufacturing, aerospace, automobile industry, powder metallurgy, biomedical microelectronics industry. Among them, laser welding of thin plates is mainly used in the aerospace industry and automobile manufacturing industry.
