  In the process of gear processing and production, the general manufacturer will arrange heat treatment process. As we all know, the heat treatment process is mainly to improve the hardness and wear resistance of the tooth surface. According to the different purposes of the gear processing process, two types of heat treatment processes are generally arranged. The following two heat treatment processes in gear processing are introduced below;
  1. Blank heat treatment: firstly, preliminary heat treatment is carried out by normalizing or quenching and tempering before and after gear blank processing. The purpose of heat treatment is mainly to eliminate the residual stress generated by forging and rough machining, and improve the cutting performance of the material.
  2. Tooth surface heat treatment: After the tooth shape processing is completed, in order to improve the hardness and wear resistance of the tooth surface, it can be realized by heat treatment processes such as carburizing and quenching, high-frequency quenching, carbonitriding and nitriding; gear heat treatment
  methods There are many kinds, and the commonly used ones are overall quenching, high-frequency quenching, nitriding, carburizing quenching, vacuum quenching, etc. In the actual production demand, we can choose the corresponding heat treatment method according to the different requirements of gear processing.
