How to Inspect The Quality of Laser Cutting Machines?

1. Roughness

Laser cutting cross section will form a vertical lines, the depth of the texture of the cut surface of the roughness of the cut surface, the more shallow lines, the more smooth cut section. Roughness not only affects the appearance of the edges, but also affect the friction characteristics, in most cases, it is necessary to minimize the roughness, so the more shallow texture, the higher the quality of the cut.

2. Verticality

If the sheet thickness exceeds 10mm, the verticality of cutting edge is very important. Away from the focus, the laser beam becomes divergent, according to the location of the focus, cutting to the top or bottom of the variable width. Cutting edge off the vertical line of a few millimeters, the edge of the more vertical, the higher the quality of cutting.

3. Cutting width

Kerf width generally does not affect the cutting quality, only in the internal components formed special precision contour, cutting width is important. This is because the cutting width determines the contour of the minimum, when the plate thickness increases, the cutting width also increases. So want to guarantee the same high precision, no matter how much the width of the cut, the workpiece in the laser cutting machine processing area should be constant.

4. Lines

High speed cutting thick plate, the molten metal will not appear in the vertical laser beam below the incision, but will be sprayed out at the laser beam side. As a result, the curved lines are formed on the cutting edge, and the lines are closely followed by the laser beam. In order to correct the problem, the feed rate can be reduced at the end of the cutting process.

5. Burr

Burr formation is a very important factor to determine the quality of laser cutting, because the removal of burr need extra work, so the amount of burr is serious and how much is able to directly determine the quality of cutting.

6. Material Deposition

Laser cutting machine before the beginning of melting and perforation of the workpiece surface with a layer of oil on the surface of a special liquid. Gasification and all kinds of materials, the material does not need to use the wind to blow the cut, but the upward or downward discharge also can form the deposition on the surface.

7. Sag and Corrosion

Sag and corrosion have adverse effects on the surface of the cutting edge, affecting the appearance. They appear in the error of the cut which is generally supposed to be avoided.

8. Heat Affected Zone

In laser cutting, the area near the notch is heated. At the same time, the structure of the metal changes. For example, some of the metals can be hardened. The heat affected zone refers to the depth of the area that is changed by the internal structure.

9. Deformation

If the cutting makes the component heat, it will deform. This is particularly important in fine processing, because the profile and connecting pieces are usually only a few millimeters wide. Control of laser power and the use of short laser pulses can reduce the parts to become hot, to avoid deformation.
