The use of high power density laser beam irradiation is cut material, so that the material is quickly heated to the temperature of vaporization, evaporation formed holes, with the movement of the beam of the material, the hole continuous formation of a very narrow width (such as about 0.1mm) slit, complete the cutting of the material.
⑴ Good cutting quality. Because of the small spot, high energy density and fast cutting speed, laser cutting can obtain better cutting quality.
(2)Due to the transmission characteristics of laser, laser cutting machine is generally equipped with a number of numerical control table, the whole cutting process can be realized CNC. When operating, just change the numerical control program, it can be suitable for cutting parts of different shapes, not only can be two-dimensional cutting, but also can realize three-dimensional cutting.
⑶ Fast cutting speed
Using 1200W laser cutting 2mm thick low carbon steel plate, cutting speed up to 600cm/min; Cutting 5mm thick polypropylene resin board, cutting speed up to 1200cm/min. The material does not need to be fixed when the laser cutting, which can save the fixture, and save the auxiliary time of loading and unloading.
(4) Non-contact cutting
Laser cutting torch and workpiece no contact, there is no tool wear. Processing parts of different shapes, do not need to replace the "tool", just change the output parameters of the laser. Laser cutting process has low noise, small vibration and no pollution.
