There are many cutting methods for laser cutting machines, among which melting cutting is a relatively common one. So how much do you know about this cutting method? Let's introduce to you in detail what is the melting cutting method of laser cutting machine. The melting and cutting method of    laser cutting machine is to use several heating workpieces with a certain power density to melt them, and at the same time, rely on the non-oxidizing auxiliary airflow coaxial with the beam to blow off and take away the molten material around the hole to form a slit. The laser beam irradiates the surface of the workpiece, except for the reflection loss, the remaining energy is absorbed, heating the material and evaporating into a small hole; once the small hole is formed, it will absorb all the beam energy as a black body, and the small hole is surrounded by the molten metal wall. The high-speed steam flow keeps the melt wall relatively stable; the    melting isotherm penetrates the workpiece and blows away the molten material by the auxiliary air jet pressure; as the workpiece moves, the small hole moves laterally and leaves a slit, and the laser beam continues along The leading edge of this slit is irradiated, and the molten material is continuously or pulsatingly blown away from the slit. For thin plate materials, the cutting speed is too slow, most of the laser beam will directly pass through the incision to lose energy. The increase in speed will make more beams irradiate the material, increase the coupling power with the material, and obtain a wider parameter adjustment zone to ensure the cutting quality. For plate material, occasionally the laser evaporation effect or the melting product removal speed is not fast enough, the beam reflects multiple times on the cut surface of the material in the slit. As long as the melting product can be removed before it is condensed by the cold air flow, the cutting process will continue.
