First, check whether the material cut surface processed by the laser cutting machine is smooth and clean, whether there are patterns, and whether there are brittle fractures; When the optical fiber laser cutter cuts steel plates with high speed laser, molten metal materials are not easy to appear in the wound directly below the vertical particle beam, instead, they will drip out at the back of the particle beam. As a result, the bent texture is generated at the laser cutting edge, and the texture firmly follows the moving particle beam in order to adjust this problem. The cutting speed is reduced at the end of the laser cutting production process, which can greatly eliminate the formation of the texture.

The total width of the cutting slot is narrow, which is mainly related to the diameter of the particle beam spot; Generally, the total width of the wound of the optical fiber laser cutting machine does not harm the quality of the laser cutting. It is only when there is a very hardware mechanical contour inside the component that the total width of the laser cutting is critical. This is because the total width of the laser cutting determines the minimum inner diameter of the contour. When the plate is thin and thick, the total width of the laser cutting will increase accordingly. Therefore, we are willing to ensure the same high precision, regardless of the total width of the wound, and the steel parts should move at a uniform speed in the production and processing area of the laser cutting machine.

Good kerf flatness and small thermal hazard area; Generally, the key of optical fiber laser cutting machine is focused on the production and processing of raw materials below 5Mm, and the flatness of its cross section will not be a more critical assessment factor. However, for high-power laser cutting, when the thickness of raw materials for production and processing exceeds 12mm, the flatness of the laser cutting edge is very critical. When focusing is eliminated, the particle beam will converge more and more, and the laser will become wider towards the top or bottom according to the focusing position. The laser cutting edge is offset by a few percent of the bisector. The more vertical the edge is, the higher the laser cutting quality is.

No raw materials are ignited, no melting layer is produced, and no large slag is produced; The key reflection of slag hanging in metal material laser numerical control cutting is igneous rock and the rough edge of cross section. At least the raw material igneous rock meets with layers of unique liquid with oil content on the surface of the steel piece before the laser cutting starts to melt and break the hole. Vaporized and various raw materials do not require customers to gently blow the wound with wind, but the upward or downward discharge will also produce igneous rock on the surface. The generation of burrs is a very critical hazard factor in determining the quality of laser cutting. Because the removal of burrs requires additional labor, the amount of burrs is relatively serious and how much is the quality of laser cutting that can be visualized.

The wound surface is not smooth, and the size of roughness is important to consider the performance of laser cutting technology. I think that for the optical fiber laser cutting machine, the cross section texture and surface roughness of laser cutting have an immediate connection. Therefore, the main performance of laser cutting with poor cross section texture will immediately lead to high surface roughness. However, fully considering the differences in the inducements of the two different practical effects, people usually analyze the production and processing quality of metal material laser numerical control cutting by separating them. Laser cutting cross section will produce vertical texture. The depth of texture 1 determines the surface roughness of laser cutting surface. The lighter the texture, the more smooth the laser cutting cross section. The surface roughness not only harms the appearance of the edge, but also the friction characteristics. In most cases, the surface roughness must be reduced as much as possible. Therefore, the lighter the texture, the higher the laser cutting quality.
