Three characteristics of 15000w ultra high power CNC fiber laser cutting machine laser.

1. The signal transmission takes the form of electricity light electricity, and the light emitting part and the light receiving part are not in contact, which can avoid the possible feedback and interference from the output end to the input end;

2. Strong ability to suppress noise interference;

3. It has the advantages of durability, high reliability and fast speed. The response time is generally within a few, and some of the response time of high-speed optocouplers are even less than 10ns.

Therefore, when designing the system circuit of super power NC fiber laser cutting machine, we should pay attention to the isolation between the input signal circuit and the single chip microcomputer. Here, photoelectric coupling is the most commonly used method.

In the metal processing industry, which plays a very important role in the industrial manufacturing system, many metal materials can be cut without deformation regardless of their hardness. Of course, for high reflectivity materials, such as gold, silver, copper and aluminum alloys, they are also good heat transfer conductors, so laser cutting machines are difficult or even unable to cut. Although the technology of ultra-high power fiber laser cutting machine has obvious advantages, as a high-tech equipment, in order to use ultra-high power fiber laser cutting machine to achieve the ideal cutting effect, we must also master its processing technical parameters and operation process. Especially in the cutting process of metal NC optical fiber laser cutting machine, it is necessary to select the appropriate cutting speed, otherwise several bad cutting results may be caused, mainly as follows:

1. When the laser cutting speed is too fast, the following adverse results will be caused:

Unable to cut, spark spraying;

The cutting surface presents oblique lines, and the lower half produces molten stains;

The whole section is thick, but there is no melting stain;

2. On the contrary, when the laser cutting speed is too slow, it will cause:

Cause over melting and rough cutting surface.

The slit widens and melts at the sharp corner.

Affect cutting efficiency.

Therefore, in order to make the super power CNC optical fiber laser cutting machine give better play to its cutting function, whether the feed speed is appropriate can be judged from the cutting spark of the laser equipment:

1. If the spark diffuses 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 show non-diffusion and less agglomeration, it indicates that the speed is too slow.

Compared with other traditional cutting methods, laser cutting technology has incomparable obvious advantages. Laser cutting machine not only has the main characteristics of narrow cutting seam and small workpiece deformation, but also has the characteristics of high speed, high efficiency, low cost, safe operation and stable performance.

In recent years, with the rapid improvement and development of ultra-high power laser, its application in industry has developed from only used for the processing of small or micro structures to widely used for the processing of large structural parts. It has attracted more and more attention and recognition, and is widely used in machinery manufacturing, aerospace, automotive industry, powder metallurgy Biomedical microelectronics industry and other industrial fields. The numerical control optical fiber laser welding machine for thin plate is mainly used in aerospace industry and automobile manufacturing industry.
