Machining parts with the corresponding heat treatment process first can make the accuracy and service life of machined parts greatly enhanced, which helps to improve the hardness, wear resistance and strength of machined parts. Machining is a process that uses machine tools and equipment to process parts.

Then how to heat treatment of machined parts, machining of parts before and after processing will be the corresponding heat treatment process.

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

2. To improve the processing conditions. etc. Make the material easy to process. Such as annealing, normalizing. Tempering treatment.

3. Improve the overall mechanical properties of metal materials.

      4. Can improve the hardness of the material. Such as carburizing, quenching, etc.
