With the rapid development of laser cutting technology, optical fiber laser cutting machine has been widely used to cut metal plates. So the quality of the workpiece after laser cutting and the cutting effect are all matters of concern to customers. This requires a standard to judge the cutting quality, which is also the most intuitive way to judge the performance of optical fiber laser cutting equipment, Now let's take a look at the standards for judging the cutting quality of optical fiber laser cutting machine?

1. Roughness: The laser cutting section will form vertical lines. The depth of the lines determines the roughness of the cutting surface. The shallower the lines, the smoother the cutting section.

2. Verticality: How to make the thickness of the sheet metal exceed 10mm, the perpendicularity of the cutting edge is very important. When it is far away from the focus, the laser beam becomes divergent, and the cutting becomes wider toward the top or bottom according to the location of the focus. The cutting edge deviates from the vertical line by several millimeters. The more vertical the edge is, the higher the cutting quality is.

3. Cutting width: generally speaking, the cutting width does not affect the cutting quality. Only when a particularly precise contour is formed inside the part, the cutting width has an important impact. This is because the cutting width determines the minimum internal diameter of the contour. When the plate thickness increases, the cutting width also increases. Therefore, in order to ensure the same high accuracy, no matter how wide the incision is, the workpiece in the processing area of the optical fiber laser cutting machine should be constant.

4. Texture: When cutting thick plates at high speed, molten metal will not appear in the incision below the vertical laser beam, but will spray out at the back of the laser beam. As a result, bent lines are formed at the cutting edge, and the lines closely follow the moving laser beam. To correct this problem, reducing the feed rate at the end of the cutting process can greatly eliminate the formation of lines.

5. Burr: It is a very important factor that determines the quality of laser cutting when the burr is formed. Because the removal of burr requires additional work, the severity and amount of burr can directly judge the quality of cutting.

6. Material deposition: Before the optical fiber laser cutting machine starts to melt and perforate, it first touches a layer of special oil containing liquid on the workpiece surface. During the cutting process, due to gasification and various materials are not used, the customer blows the cut with wind, but the upward or downward discharge will also form deposits on the surface.

7. Deformation: If the cutting makes the part heated sharply, it will deform. This is particularly important in fine machining because the profile and connecting piece here are usually only a few tenths of a millimeter wide. Controlling the laser power and using short laser pulses can reduce the heating of components and avoid deformation.

The above are some standards for us to judge the cutting quality in the field of laser cutting. Of course, different people have different opinions. The above is only a reference standard.
