What gas does laser cut copper plate use?
Laser cutting is not visible by light beam to replace the mechanical knife, which has the advantages of high precision, fast cutting, cutting pattern is not limited to the limit, automatic typesetting and material saving, incision smooth, low processing cost, will gradually improve or to replace the traditional metal cutting equipment. The mechanical part of laser cutter head and the workpiece without contact, not at work to scratch the surface of the workpiece; the laser cutting speed, smooth incision, generally without the need for subsequent processing; cutting small heat affected zone, the deformation is small, narrow kerf (0.1mm~0.3mm); incision without mechanical stress, shear free burr; high precision, good repeatability, no damage to the material surface; NC programming and machining of arbitrary planar graphs, the whole plate large format cutting, no need to open mold, time saving.
Laser cutting is a laser beam emitted from a laser and focused on a laser beam with high power density via an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach a melting point or boiling point, while a high-pressure gas coaxial with the beam will blow or blow away the metal. With the relative movement of the beam and the workpiece, the material is eventually formed into slits to achieve the purpose of cutting.
Laser is a kind of light, which, like other natural light, is produced by the transition of atoms (molecules, ions, etc.). But it is different from ordinary laser light only in a very short time depends on the initial spontaneous emission, then the process is completely determined by the laser radiation, so the laser has a very pure color, high directivity, almost no divergence of the luminous intensity and high coherence.
