As a processing industry, the requirements for product processing quality are very strict, so the requirements for equipment are also very high. As the equipment in metal processing, metal laser cutting machine has good advantages in product processing, with relatively low cost consumption, which is more beneficial to enterprises.
Although the processing effect of metal laser cutting machine is very good, it depends not only on the quality of the equipment itself, but also on other external factors. Let’s give you a detailed analysis
Factors influencing the processing quality of metal laser cutting machine
1. The influence of cutting speed on cutting quality; The processing speed of the metal laser cutting machine is too fast, which may lead to the impermeable cutting of the workpiece, or too slow, which may lead to the problem of cutting residues and burning edges. According to the actual thickness of the workpiece, calculate and adjust the parameters to test the cutting, so as to achieve a good cutting speed.
2. Selection of focus position of metal cutting machine; It is very important to determine the corresponding position of the focus and the material surface, which is directly related to the cutting quality. The power at the focal point is very high, and in most cases, the focal point is located on or below the surface of the cutting material. When the focus is in a good position, the gap is small, the efficiency is high, and good cutting speed can obtain good cutting effect.
3. The influence of auxiliary gas on cutting effect; As mentioned earlier, different gases have different performance in cutting effect. In addition, the pressure of the auxiliary gas will also have a certain impact on the cutting effect. When laser cutting machine is used to cut some thin materials at high speed, higher air pressure is usually required to prevent slag from adhering to the back of the cut. If the thickness of the material increases or the cutting speed slows down, the air pressure of the auxiliary gas should be reduced. At the same time, in order to prevent the plastic cutting edge from frosting, cutting should also be carried out under low air pressure.
4. The influence of cutting material characteristics on cutting quality; Different metal materials have different characteristics and different laser absorption capacity, so the cutting effect of metal laser cutting machine is also different. For example, high reflectivity materials (aluminum, copper) are difficult to cut. The other is the treated materials. The surfaces with film coating and other surface treatments are also difficult to cut (depending on the situation).
