Changan laser cutting processing explains how to do product deformation?

The beam of light in Changan laser cutting is focused into a very small light spot, so that the focal point reaches a high power density. At this time, the heat input by the beam of light far exceeds the part reflected, conducted or diffused by the material, and the material is quickly heated to the degree of vaporization, evaporating to form holes. As the beam of light moves relatively linearly with the material, the hole continuously forms a slit with a very narrow width. The trimming is little affected by heat, and there is basically no workpiece deformation.

When numerical control machining, the action of the laser beam will form a pit in the material, and at the same time, the generated airflow will form a hole in the material, which is what we call the puncture point. When penetrating the steel plate, the cutting speed of the laser beam will change greatly, and finally the cutting is completed.

The most common type of stamping parts processing is air, which can be directly used as a cutting gas, and can also be used in cooling, internal dust removal, etc. Ordinary oxygen is another type of gas that is often used in the cutting process, mainly for carbon steel cutting; if the cutting is made of stainless steel, 100% pure nitrogen is used, and this gas can also be used as a raw material for lasers.
