Laser cutting technology is widely used in metal and non-metallic materials processing, can greatly reduce the processing time, reduce processing costs, improve the quality of the workpiece. Pulsed lasers are suitable for metal materials, continuous lasers for non-metallic materials, and the latter are important areas of laser cutting technology. The modern laser has become the "sword" of the "iron-cut" people's dreams.
Laser cutting is focusing the CO2 laser beam onto the surface of the material to melt the material with a focusing mirror while blowing away the melted material with a compressed gas coaxial with the laser beam and causing the laser beam to move relative to the material along a certain trajectory A certain shape of the slit. Since 1970s, with the continuous improvement and development of CO2 laser and numerical control technology, it has become an advanced processing method for industrial sheet metal cutting. In the fifties and sixties as the main method of cutting sheet metal cutting: oxyacetylene flame cutting for plate; for sheet cutting with cutting bed, forming a large number of complex parts stamping, vibration using a single piece of shear. Seventies, in order to improve and improve the cutting quality of flame cutting, but also promote the oxyethylene flame cutting and plasma cutting. In order to reduce the manufacturing cycle of large stamping dies, but also developed a CNC nunchuck and electrical processing technology. Cutting methods have a variety of cutting shortcomings in industrial production has a certain scope of application.
