There is currently no constant standard for the cutting quality of laser cutting machine equipment. Now it is mostly determined by looking at the specific cutting effect, but there are many factors that affect the cutting effect. In fact, in daily life, we usually check the cutting quality through these points:
1. Roughness: The laser-cut section, especially the thick sheet, will form vertical lines. The depth of the lines determines the degree of cutting roughness. The shallower the lines, the smoother the section and the better the cutting quality. Roughness greatly affects the beauty of the metal and the difficulty of other processing in the later stage. So in most cases, the shallower and finer the texture, the lower the roughness and the better the quality.
2. Perpendicularity: The laser beam is actually a cylinder when it is zoomed in. It is focused to form a focus and irradiates the metal material, so the laser beam is divergent at the position far from the focus, so that the top or bottom of the cut will change according to the position of the focus. If it is wide, the cutting section will form a taper, and the verticality is not obvious when cutting thin plates, but generally when cutting plates above 10mm, the verticality is very important. The more vertical the cutting edge, the higher the quality of the cut.
3. Slag and burrs: The slag is mainly reflected in the burrs deposited on the cutting section. During the laser cutting process, gas will blow away the melted or vaporized material residue, but no matter how much up or down it will be in the The formation of deposits on the surface and the presence of burrs in the cutting are a factor that greatly affects the cutting quality, which will increase the extra processing volume and increase the processing cost. The burr can be clearly seen, so it is also a factor to directly judge the cutting quality.
4. Heat-affected zone: Laser cutting is a thermal processing equipment, which will inevitably have a thermal impact on the metal during the cutting process. The laser generates a lot of heat during the cutting process, which is affected along the vicinity of the cut, causing changes in the interior of the metal, and some metals will harden. If the material is heated sharply during the cutting process, it can also cause deformation of the material, which is important in many fine processes. Controlling the laser power or using short laser pulses can reduce part heating and avoid deformation.
Baiwei Laser is located in Zhengzhou, the important birthplace of Chinese civilization in China. At present, it has a good R&D team, a number of domestic and foreign certificates and computer software copyrights, and many of its important technologies are at the international level. The company has established strategic cooperative relations with the national multi-industrial machinery industry, etc., and jointly established projects such as talent training, industrial manufacturing, R&D and production. In terms of production, according to ISO9001 quality control system and ISO14001 environmental management system, to ensure product performance and quality, and many series of products have obtained EU CE certification.
