With the popularization of optical fiber laser cutting machine, people are more and more familiar with it. What are the main processing methods of optical fiber laser cutting machine?
The processing methods of optical fiber laser cutting machine mainly include vaporization cutting, oxidation melting cutting, melting cutting and controlled fracture cutting. Let's take a look at the vaporization cutting of optical fiber laser cutting machine.
During the vaporization cutting process of the optical fiber laser cutting machine, the surface temperature of the metal material rises to the boiling point temperature very quickly, which is enough to avoid melting caused by heat conduction, so some materials vaporize into steam and disappear, and some materials are blown away from the bottom of the cutting seam by the auxiliary gas flow as ejecta. This situation requires a high-power laser generator.
In order to prevent metal material vapor from condensing on the slit wall, the thickness of the material must not exceed the diameter of the laser beam. Therefore, the processing is only suitable for applications where the exclusion of molten materials must be avoided. In fact, the processing is only used in very small application fields of iron base alloys.
This process cannot be used for wood and some ceramics, which have no melting state and are unlikely to allow the material vapor to condense again. In addition, these materials are usually required to achieve a thicker cut. In laser vaporization cutting, the optimal beam focusing depends on the material thickness and beam quality. Laser power and heat of vaporization have only certain effects on the optimal focus position. The maximum cutting speed is inversely proportional to the gasification temperature of the material when the thickness of the plate is fixed. Under the condition that the thickness of the plate is fixed, assuming that there is sufficient laser power, the maximum cutting speed is limited by the gas jet speed.
