Machining is a processing technology that uses machine tool equipment to process parts. Machining will carry out corresponding heat treatment processes before and after machining parts, so why heat treatment of machined parts?

1. Remove the internal stress of the blank. Mostly used for castings, forgings, welded parts.

2. Improve processing conditions and make materials easy to process. Such as annealing, normalizing, etc.

3. Improve the comprehensive mechanical properties of metal materials. For example, conditioning treatment.

4. It can improve the hardness of the material. For example, quenching, carburizing quenching, etc.

The machining parts are subjected to the corresponding heat treatment process, which helps to improve the hardness, wear resistance and strength of the machined parts, and greatly enhances the accuracy and service life of the machined parts.
