There are many standards that affect the cutting quality of laser cutting machine, but which ones are more influential or can better reflect the quality of laser cutting machine?
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. In most cases, the roughness needs to be reduced as much as possible, so the shallower the grain, the higher the cutting quality.
2. Verticality. If the thickness of the sheet metal exceeds 10mm, the perpendicularity of the cutting edge is very important. When it is far away from the focus, the laser beam becomes divergent. According to the location of the focus, the cutting becomes wider toward the top or bottom. 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, the cutting width has an important impact. This is because the cutting width determines the smaller internal diameter of the contour. When the thickness of the plate increases, the cutting width also increases.
4. Texture. When cutting thick plates at high speed, molten metal will not appear in the incision below the vertical laser beam, but will spray out at the back of the laser beam. As a result, the curved lines of the laser cutting machine are formed at the cutting edge, and the lines closely follow the moving laser beam. To correct this problem, reducing the feed rate at the end of the cutting process can greatly eliminate the formation of lines.
5. 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.
When using the metal laser cutting machine, we should pay attention to the fire prevention measures, and take good fire prevention measures to ensure our safety when using the metal laser cutting machine. Therefore, we should know the fire prevention precautions when using the metal laser cutting machine
1. When using the metal laser cutting machine, check whether the gas path is completely sealed. If leakage occurs, it will lead to the combustion of these flammable gases;
2. The use of metal laser cutting machine is better to keep away from open fire, otherwise it is easy to cause fire due to high temperature;
3. Do not let the light spot of the metal laser cutting machine stay in one place all the time to effectively prevent fire
