Quenching

Home page

Laser quenching is used for the tooth surface, which has a high heating and cooling rate, a short process cycle, and does not require external quenching media It has unique advantages such as small workpiece deformation, clean working environment, no need for precision machining such as grinding after processing, and the size of the processed gear is not limited by the size of the heat treatment equipment

Laser quenching has high power density, fast cooling speed, and does not require cooling media such as water or oil, making it a clean and fast quenching process. Compared with induction quenching, flame quenching, and carburizing quenching processes, laser quenching has a uniform hardening layer, high hardness (generally 1-3HRC higher than induction quenching), small workpiece deformation, easy control of heating layer depth and heating trajectory, and easy automation.
