How to judge the cutting quality of the cutting machine?


The quality of the cutting of a laser cutting machine can generally be determined intuitively through the surface. Raytu laser lists 8 basic standards for everyone.

1 verticality

The thickness of the sheet metal exceeds 10mm, and the verticality of the cutting edges is very important. When it is far from the focus, the laser beam will become divergent, and the cutting will be widened at the top or bottom according to the focus position. When there is an error in the line, the more vertical the edge of the cutting, the higher the cutting quality.

2 cutting line

In the process of high-speed cutting thick plates, the melting metal usually does not appear inside the incision below the vertical laser beam, but it will rush out from the position of the laser beam. In the end, the curved lines were formed at the edge of the cut, and these patterns followed the mobile laser beam closely. To effectively correct this problem, when cutting and processing are close to the end, reducing the rate of advancement, can greatly eliminate the formation of texture.


3 Cutting surface roughness

The depth of the pattern formed by the laser cutting surface determines the roughness of the cutting surface. The lighter the texture, the smoother the cutting surface, and the higher the cutting quality.

4 The width of cutting

Under normal circumstances, the incision width will not affect the cutting quality. Only when the inside of the component is extremely fine, the cutting width will have a key role. This is because the cutting width determines the minimum inner diameter of the contour, and as the thickness of the plate increases, the cutting width will increase accordingly.

5 burrs

The formation of burrs is an important factor that affects the quality of laser cutting. Given the additional workload of the removal of the burrs, the weight of the amount of burrs and how much can intuitively determine the quality of cutting.


6 depression and corrosion

Depression and corrosion will have adverse effects on the surface of the cut edge and affect its appearance. They exist in cut errors that are usually avoided.

7 Thermal impact area

During the use of laser cutting, the surroundings of the incision will be heated, which will easily cause changes in the metal structure, such as hardening metal. Such a region is the heat affecting the area.

8 Deformation situation

Especially in fine processing, the contour and connecting films are generally only a dozen millimeters or even a few millimeters wide. When cutting, the parts will be heated sharply causing deformation. It can avoid deformation by controlling the power of the laser or using short laser pulses.
