Laser hardening process of the laser cutting machine is a new process has many characteristics of surface hardening treatment.
The main features are: (
1)
High speed heating and high speed on the surface of the material 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, thus heat affected zone is small, quenching stress and deformation is small.
（
4)
To 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.
