The cutting quality of optical fiber laser cutting machine is the most concerned by customers. At the same time, it is also a skill training that craftsmen need to constantly improve. However, in order to cut satisfactory samples, it is necessary to use optical fiber laser cutting machine scientifically. 

Let's take a look at the evaluation criteria of cutting quality and the methods of realizing high quality cutting from the following three points:

1.The cutting section is smooth, the grain is less, and there is no brittle fracture. When the optical fiber laser cutting machine is cut, the cutting marks will be displayed after the laser beam deviates. So a laser slight reduction in the rate at the end of the cutting process can eliminate the formation of the pattern.


2.The cutting slit width. The size of the slit is related to the thickness of the cutting plate and the size of the nozzle. In general, if the metal plate is thin, the nozzle selected will be small, because the amount of assist gas required is relatively small. Similarly, if the metal plate is thick, it needs more assist gas, so the nozzle is also large, and the cutting seam will be widened accordingly. So we have to look for the right type of nozzle in order to cut out a good product.

3.The cutting verticality is good and the heat affected area is small. The verticality of the edge is a very important element of laser cutting. The laser beam diverts when away from focus, depending on the position of the focus, the cut widens toward the top or bottom, the more vertical the edge, the higher the cutting quality.
