When machining parts, first carry out the corresponding heat treatment process, which can greatly enhance the accuracy and service life of the machined parts, which helps to improve the hardness, wear resistance and strength of the machined parts. Machining is a kind of processing technology that uses machine tools to process parts. So how to heat treat the machined parts? The corresponding heat treatment process will be carried out before and after machining.

1. Remove the internal stress of the blank. It is mainly used for castings, forgings and weldments.

2. Improve processing conditions. Wait. Make the material easy to process. Such as annealing and normalizing. Quenching and tempering treatment.

3. Improve the comprehensive mechanical properties of metal materials.

4. It can improve the hardness of materials. Such as carburizing, quenching, etc.
