The final heat treatment of mechanical parts processing is to improve the mechanical properties of parts, such as hardness, wear resistance and strength, so as to better realize their use value. Do you know the specific purpose of heat treatment for machining mechanical parts? Let's share with you today!
1. Remove the internal stress of the blank. It is mainly used for castings, forgings and weldments.
2. Improve processing conditions to make materials easy to process. Such as annealing, normalizing, etc.
3. Improve the comprehensive mechanical properties of metal materials. For example, quenching and tempering treatment.
4. Obtain hardness. For example, quenching, carburizing and quenching, etc.
The above content is the reason for heat treatment of mechanical parts processing, and I hope it can help you!
