The metal processing industry plays an important role in the industrial design and manufacturing system, and many metal materials, no matter what kind of hardness, can be cut without deformation. Therefore, super power fiber laser cutting machine technology has obvious advantages, but as a high-tech equipment, to use super power fiber laser cutting machine to achieve the ideal cutting processing effect, it is also necessary to master its processing technical parameters and operation process. Especially in the metal laser cutting machine cutting process, it is necessary to choose the right cutting speed, otherwise it may cause several bad cutting results, which are mainly as follows:
1, when the laser cutting speed is too fast, it will cause the following adverse results:
① cause can not cut, spark spray phenomenon;
② Cause the cutting surface to show diagonal lines, and the lower part of the melting;
③ The whole section is thick, and there is no melting;
2, on the contrary, when the laser cutting speed is too slow, it will cause:
① The cutting surface is rough, resulting in over-melting.
② The slit becomes wider and melts the whole at the sharp corner.
③ Affect the efficiency of cutting.
Therefore, in order to make the super power fiber laser cutting machine equipment better play its cutting function, you can judge whether the feed speed is appropriate from the laser cutting spark:
(1) If the spark spreads 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 spark is nondiffuse and less, and condensed together, it indicates that the speed is too slow.
Compared with other traditional cutting methods, laser cutting technology has obvious advantages that cannot be compared. Laser cutting machine not only has the main characteristics of narrow slit, small deformation of the workpiece and laser cutting has fast speed, high efficiency, high quality, high reliability, first-class cutting quality, improve production efficiency, and shorten the production cycle. Mastering the use and nature of laser cutting machine can make industrial production in all walks of life reach a higher milestone.
