Factors affecting the cutting effect of laser cutting machine1

Laser cutting machines have been developed for many years and have gradually become the mainstream processing equipment for metal processing. There will always be some problems when cutting, such as too large cutting gaps. So what are the factors that affect the cutting effect of the laser cutting machine? There are mainly the following four points:

First, the quality of the laser beam

The laser beam produced by the laser is not emitted vertically, but has a scattering angle. Therefore, when we use the laser cutting machine to cut the workpiece, a certain taper will be formed, so the quality of the laser beam is also very important when cutting. Generally, the focus point should not be arbitrarily adjusted after adjustment, but only need to be adjusted when there are obvious problems with the cutting effect.

Two. Different cutting materials

According to the different cutting materials, the actual effect of cutting is also different. In laser cutting, the smaller the laser beam spot, the better the cutting effect. In addition to the quality of the laser beam affecting the spot, the material of the workpiece itself also affects the size of the spot. For example, copper is a material with high reflectivity, which is not conducive to the formation of light spots. Therefore, the requirements of copper laser cutting machines are relatively high compared to ordinary metals.

3. Material thickness

Under the same material, the same power cutting conditions, the larger the thickness of the material when cutting, the section is relatively burr, uneven. To be completely the same as the cross-section of the thin plate material, the power of the laser needs to be increased.

Four. Cutting speed

The reason why laser cutting machines are respected is partly because of the fast cutting speed. If other conditions remain unchanged, the cutting speed of the laser cutting machine is too slow or too fast to achieve a good cutting effect. If the speed is too slow, the roughness of the gap may be large, and if the speed is too fast, the roughness of the gap may decrease. However, if the speed is too fast, the phenomenon of impenetrability may appear, so it is very important to control the speed, and you cannot blindly pursue high-speed cutting.
