Metal laser cutting machine laser hardening treatment process characteristics

Metal laser cutting machine laser hardening treatment process features: 1, the material on the surface of the high speed heating and high speed from the cold. 2, after the laser hardening treatment of workpiece surface hardness, 5% ~ 20% higher than conventional quenching, very fine organization of hardening layer can be obtained. 3, due to the laser heating speed and heat affected zone is small, the quenching stress and deformation is small. 4, to the complex shape parts and other conventional methods cannot be used local hardening treatment processing of parts. At the same time, also can according to need to be done in different parts of the same parts of different laser hardening treatment. 5, laser hardening process cycle is short, high production efficiency, process computer control, easy to realize automation degree is high, it can be incorporated into the production line. 6, laser hardening by its excellent heat conduction from the cold, without cooling medium, no pollution to the environment.
