At present, there is no constant standard for the cutting quality of laser cutting machine equipment, which is mostly determined by the specific cutting effect, but there are many factors that affect the cutting effect. In fact, in our daily life, we usually check the cutting quality through these points:

Laser cutting machine

1、 Roughness: Laser cut sections, 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 sections, and the better the cutting quality. Roughness greatly affects the beauty of metal and the difficulty of other processing in the later period. Therefore, in most cases, the shallower the grain, the more delicate, the lower the roughness, and the better the quality.

2、 Verticality: The laser beam is actually a cylinder when magnified. It forms a focal point to shine on the metal material through focusing, so the laser beam is divergent at the position far from the focal point. In this way, the top or bottom of the cut will become wider according to the focal point position, and the cut section will form a taper. The perpendicularity is not obvious when cutting thin plates, but perpendicularity is very important when cutting plates of more than 10mm. The more vertical the cutting edge is, the higher the cutting quality is.

3、 Scraping slag and burr: Scraping slag is mainly reflected in the burr deposited on the cutting section. During laser cutting, there will be gas blowing away the melted or vaporized material residue, but no matter how much upward or downward, there will be deposition on the surface. Cutting burr is a factor that greatly affects the cutting quality. It will increase additional processing capacity and improve the processing cost. Burr can be clearly seen, so it is also the most direct factor to judge the cutting quality.

4、 Heat affected zone: laser cutting belongs to thermal processing equipment, which will inevitably have thermal impact on metal during the cutting process. Laser generates a lot of heat in the process of cutting, and is affected along the incision, which will lead to changes in the metal interior, and some metals will harden. If the material is heated rapidly during cutting, it will also lead to material deformation, which is very important in many fine processing. Controlling the laser power or using short laser pulses can reduce the heating of parts and avoid deformation.

To sum up, if you want to know about a laser cutting machine, you should not only see the configuration price, but also the cutting quality of the laser cutting machine.
