The laser uses substance excitation to generate light. This light has a strong temperature. When contacting the material, it can quickly melt on the surface of the material to form a hole. According to the movement of the alignment point to form a cut. Compared with the traditional cutting method, this cutting method has a smaller gap and can save most of the material. Laser cutting is easier to understand, easy to learn, and has an absolute advantage in terms of the processing effect and speed required by merchants. Therefore, it is believed that in the future, laser cutting machines will be the demand of the public.
