It is well known that metal laser cutting machine is mainly used for fast cutting of food metal materials machinery and equipment. But in actual use, there are many factors that affect its cutting quality, such as speed, power and nozzle. Now laser cutting machine manufacturers to understand how these factors affect the cutting quality of metal laser cutting machine.
The speed of the metal laser cutting machine has basically the same effect on different materials. The speed is too fast, which may cause cutting failure, spark splashing, and the cross section shows a diagonal stripe-like path, which causes the cutting part to become thicker and melt the stain in the lower part. If the speed is too slow, the cutting board will melt too much, the cutting part will become rough, and the cutting seam will widen accordingly, causing the entire area to melt at smaller rounded corners or sharp corners, so that the desired cutting effect cannot be obtained. The cutting speed can be judged according to the cutting spark. Usually the cutting sparks are scattered from top to bottom, and the sparks are inclined and the feed speed is too fast. If the sparks do not spread and are few and condense together, it means that the feed speed is too slow.
The influence of power on cutting is mainly reflected in the quality of the cutting part. When the metal laser cutting machine is cutting, if the power is set too large, the entire cutting surface will melt and the cutting seam will be too large to obtain good cutting quality. The disadvantage is that when cutting, it will produce melted stains, and the cutting part will produce scars. Even if the power is too small, the workpiece cannot be cut. Especially for thicker plates, it is necessary to re-empty, cut the surface and cut the entire plate. In order to obtain stable cutting efficiency, you must rely on high-power cutting technology, including 10,000 watts of laser cutting technology.
Usually the influence of the nozzle on the cutting is mainly reflected by the non-circularity of the nozzle, which leads to the poor coaxiality of the beam and the gas flow, which leads to the inconsistency of the cut cross section or even the failure to cut.. The size of the nozzle hole has a great influence on the cutting quality and perforation quality. The larger the nozzle aperture, the worse the protective ability of the protective mirror. Melting sparks during the cutting process have a high probability of bouncing, which will shorten the life of the lens.
In addition, the cutting quality is also affected by factors such as process parameters, material quality, gas purity and beam quality. The cutting process of the powerful metal laser cutting machine promotes the rapid development of the laser cutting industry. If you want to obtain high-quality laser cutting products, you must fully master the cutting skills before operation to reduce the impact of various factors on the cutting quality. Improve the quality of cutting parts.
