There is no fixed criterion for the quality of laser tube cutting machine cutting. Most of it is determined by the specific cutting effect. In most cases, we use these points to judge the quality of laser tube cutting machine cutting. Of course, there are many materials used by the machine itself.

1. Roughness: The cross section of laser cutting, especially thick plates, will form vertical lines. The depth of the lines determines the degree of cutting roughness. The shallower the lines, the smoother the cutting surface and the better the cutting quality. Roughness affects the beauty of metal and the difficulty of other processing in the later stage. Therefore, the shallower and finer the lines, the lower the roughness, and the better the quality.

2. Verticality: The laser beam of the laser tube cutting machine is actually a cylinder when enlarged. It forms a focus through focusing and irradiates the metal material. Therefore, the laser beam is divergent at a position far from the focus. In this way, according to the position of the focus, the top or bottom of the cutting will become wider, and the cutting section will form a taper. 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 cutting quality.

3. Slag and burrs; Slag is mainly reflected in the burrs deposited on the cutting section. During the processing of the laser tube cutting machine, there will be gas to blow away the molten or vaporized material slag, but no matter whether it is upward or downward, it will form a deposit on the surface. When there are burrs in the cutting, it will greatly affect the cutting quality. It will also increase the additional processing volume and increase the processing cost. The burrs can be clearly seen, which is also a factor that can directly judge the cutting quality.

4. Heat-affected zone: Laser cutting is a hot processing equipment, and it is inevitable that it will have a thermal effect on the metal during the cutting process. The laser generates a lot of heat during the cutting process, and it is affected along the incision, which will cause changes in the metal inside, and some metals will harden. If the material is heated sharply during the cutting process of the laser tube cutting machine, it will also cause the material to deform, which is very important in many fine processing. Controlling the laser power or using short laser pulses can reduce the heat and avoid deformation.
