Machine Introduction:
Laser hardening (also known as laser heat treatment) refers to the use of high-energy laser beam as a heat source, through the laser generated by the laser generator and external light transmission and focus, the formation of a high energy beam, the workpiece surface quickly heated to the phase transition region and quickly cooled, so as to achieve the heat treatment process on the surface of metal substrate.
Compared with the traditional heat treatment method, it has the advantages of good controllability, strong directivity, high energy density, good uniformity of hardness of heat treatment layer and high degree of automation.
Machine Feature:
- Better evenness of hardening
As long as the laser can be irradiated, such as the tooth tip, cutting edge, etc., the hardness is consistent
- No need quenching water
Due to fast heating speed of the laser, the hardening can be done immediately and no need cooling medium required.
- No deformation no oxidation and decarburization
Thanks to very precise laser beam, it will be only effect on hardening area, so there is no deformation.small heat affected zone, no deformation, almost no oxidation and decarburization.
- Better hardening performance
After quenching, the hardness is uniform and the structure is fine, which is higher than the conventional quenching (2-5HRC), the hardening layer is 0.2-1.5mm deep, and the wear resistance and life can be increased by 3-5 times.
- No black hardening part
There is no black part in quenching, and the shear performance is greatly improved.
- Saving power consumption
Power consumption of 7KW/h, comparing with conventional induction heating, it is very less.
- No need skilled worker
This is an automatic CNC machine with rotary table, so operator just need to put the workpiece.
- Better working environment
The machine is equipped with good-looking enclosure and the quenching water is not required, so it can be located clean workshop.
