The quality of laser cutting machine mainly depends on its cutting quality, which is a direct way to check the quality of equipment. When purchasing equipment, you will be required to look at the laser cutting machine for proofing. In addition to the cutting speed of the equipment, the proofing is based on the cutting quality of the sample. How to check the cutting quality of the laser cutting machine company?
1. Roughness
The laser cutting section will form vertical lines. The depth of the lines determines the roughness of the cutting surface. The shallower the lines, the smoother the cutting section. Roughness not only affects the appearance of edges, but also affects the friction characteristics. In most cases, it is necessary to reduce the roughness as much as possible, so the shallower the lines, the higher the cutting quality.
2. Perpendicularity
The perpendicularity of cutting edge is very important when the thickness of sheet metal exceeds 10mm. When away from the focus, the laser beam becomes divergent, and the cutting becomes wider toward the top or bottom according to the location of the focus. The cutting edge deviates from the vertical line by several millimeters. The more vertical the edge is, the higher the cutting quality is.
3. Cutting width
Generally speaking, the cutting width does not affect the cutting quality. Only when a particularly precise contour is formed inside the part can the cutting width have an important impact. This is because the cutting width determines the minimum internal diameter of the contour. When the plate thickness increases, the cutting width also increases. Therefore, in order to ensure the same high accuracy, no matter how wide the incision is, the workpiece in the processing area of the laser cutting machine should be constant.
4. Burrs
The formation of burrs is a very important factor that determines the quality of laser cutting. Because the removal of burrs requires additional work, the severity and amount of burrs can directly determine the quality of cutting.
5. Pits and corrosion
The depression and corrosion have adverse effects on the surface of the cutting edge and affect the appearance. They appear in cutting errors that should normally be avoided.
6. Deformation
If cutting causes sharp heating of the part, it will deform. This is particularly important in fine machining because the profile and connecting piece here are usually only a few tenths of a millimeter wide. Controlling the laser power and using short laser pulses can reduce the heating of components and avoid deformation. The quality inspection of laser cutting machine company is important.
