Judging the quality of the laser cutting machine is good or bad, is the most intuitive way to determine the best way laser cutting equipment performance, here are some of the judgments listed for the nine standards.

1. Roughness: Laser cutting section will form a vertical line, the depth of the lines determine the roughness of the cutting surface, the shallower lines, the smoother cutting section. Roughness not only affects the appearance of the edges, but also affects the friction characteristics, in most cases, the roughness needs to be minimized, so the shallower the texture, the higher the quality of the cut.

2. Verticality: How the thickness of sheet metal over 10mm, the cutting edge of the vertical is very important. As you move away from focus, the laser beam becomes divergent, cutting widening toward the top or bottom depending on the focus's position. Cutting edge deviation from the vertical line a few millimeters, the more vertical edge, the higher the cutting quality.

3. Cutting Width: Notching width generally does not affect the quality of the cut. The cutting width has an important influence only when a very precise profile is formed inside the part because the cutting width determines the minimum internal dimensions of the profile. As the thickness of the plate increases , Cutting width also increases. So you want to ensure that the same high-precision, regardless of the width of the incision, the workpiece in the laser cutting machine processing area should be constant.

4 lines: high-speed cutting thick plate, the molten metal does not appear in the vertical laser beam under the incision, but will be in the laser beam partial posterior discharge. As a result, a curved line is formed at the cutting edge, and the line closely follows the moving laser beam. In order to correct this problem, the feed rate is reduced at the end of the cutting process, and the formation of lines can be largely eliminated.

5. Burr: Burr formation determines the laser cutting quality is a very important factor, because the burr removal requires additional workload, so the amount of burr is more serious and can directly determine the quality of cutting.

6. Material deposition: Laser cutting machine in the beginning of the melt before drilling a surface of the workpiece surface oil-containing special liquid. Gasification and a variety of materials without the customer blowing the wind cut, but up or down the discharge will be deposited on the surface.

7. Depression and corrosion: Depression and corrosion on the cutting edge of the surface adversely affect the appearance. They appear in the general should avoid the cutting error.

8. Heat affected zone: In laser cutting, the area around the incision is heated. At the same time, the structure of the metal changes. For example, some metals harden. The heat affected zone refers to the depth of the area where the internal structure changes.

9. Deformation: If the cutting makes the part heated rapidly, it will be deformed. This is especially important in fine workmanship, where the contours and tabs are usually only a few tenths of a millimeter wide. Controlling laser power and using short laser pulses can reduce the risk of heat build-up and avoid distortion.
