The cutting process of several laser cutting machines that you often use
Different materials need to use different cutting processes when using laser cutting machines to process, so as to ensure the efficiency and cutting effect. I believe that everyone has a certain understanding in production activities. Let's take a look at several common cutting processes of laser cutting machines. There are three main cutting processes for laser cutting machines. The first is oxidation melting cutting; melting and cutting generally use inert gas. If it is replaced by oxygen or other active gases, the material will be ignited under the irradiation of the laser beam, and the oxygen will be violently ignited. Another source of heat generated by the chemical reaction is called oxidative melting and cutting. The second type is controlled fracture cutting; for brittle materials that are easily damaged by heat, high-speed and controllable cutting is performed by laser beam heating, which is called controlled fracture cutting. The main content of this cutting process is: the laser beam heats a small area of u200bu200bthe brittle material, causing a large thermal gradient and severe mechanical deformation in this area, leading to the formation of cracks in the material. As long as the uniform heating gradient is maintained, the laser beam can guide the cracks to be generated in any required direction to ensure the normal operation of the laser cutting machine. The third type is melting and cutting; when the power density of the incident laser beam exceeds a certain value, the inside of the material at the point where the beam is irradiated will evaporate, forming holes. Once this small hole is formed, it will act as a black body to absorb all the incident beam energy. The small hole is surrounded by a wall of molten metal, and then the auxiliary airflow coaxial with the beam takes away the molten material around the hole. As the workpiece moves, the small hole moves synchronously in the cutting direction to form a slit. The laser beam continues to irradiate along the leading edge of this slit, and the molten material is continuously or pulsatingly blown away from the slit.
