Laser cutting technology
The laser beam is focused on the surface of the material by means of a focusing lens to melt the material while blowing the molten material with the compressed gas coaxial with the laser beam and the relative movement of the laser beam and the material along a certain trajectory to form a certain shape Of the slits. Since the seventies of the twentieth century with CO2 lasers and numerical control technology continues to improve and develop, has become an industrial plate cutting an advanced processing methods. In the fifties and sixties as the main method of cutting off the plate for the plate with oxygen acetylene flame cutting for the use of shear sheet cutting sheet, forming complex parts of the use of large quantities of stamping, single use of vibration shear. After the seventies, in order to improve and improve the quality of flame cutting incision, but also to promote the oxygen oxide precision flame cutting and plasma cutting. In order to reduce the manufacturing cycle of large stamping dies, but also the development of numerical control nibbling and electrical processing technology. All kinds of cutting and cutting methods have their own shortcomings, in industrial production has a certain scope of application.
