Importance Of Heat Treatment After CNC Processing

There are many follow-up processes commonly used in cnc precision machining, such as heat treatment, surface treatment. These machining processes are to make precision parts more practical.

Heat treatment includes three stages: heating, heat preservation and cooling. The main factors at work in heat treatment are temperature and time.

Heat treatment is the heating of steel in solid state to a certain temperature, carry out the necessary heat preservation, and cool it to room temperature at an appropriate speed to change the internal structure of the steel to obtain the required performance.

In CNC precision machining, heat treatment is to improve the mechanics function of mechanical parts, to ensure that the processing quality meets the needs of commodity use.

The importance of heat treatment is as follows:

1. The purpose is to change the internal structure of the steel to improve the performance of the steel.
2. Proper heat treatment can significantly improve the mechanical properties of steel and prolong the service life of machine parts.
3. Heat treatment process can not only strengthen metal materials to fully tap the potential of material performance, reduce the weight of the structure, save materials and energy, but also improve the quality of mechanical products, greatly extend the service life of machine parts.
4. Proper heat treatment process can eliminate various defects caused by hot processing processes such as casting, forging and welding, refine grain size, eliminate segregation, reduce internal stress, and make the structure and performance of steel more uniform.
