There are many common machining processes used in the processing of precision hardware parts, such as calcination, heat treatment, surface treatment, etc., all of which are designed to make precision parts more practical.
Next, we will focus on the importance of heat treatment of precision hardware machining:
Heat treatment contains: heating, holding and cooling three stages. Temperature and time are the main factors of heat treatment.
Heat treatment is to heat the steel under solid to a certain temperature and cool to room temperature at a suitable rate to change the internal organization of the steel, and then get
to the desired properties.
In precision hardware machining, heat treatment is used to improve the mechanical function of mechanical parts and to ensure that the machining quality meets the requirements of the product application.
The importance of heat treatment in precision parts processing plant is as follows.
1. Its purpose is to change the internal structure of steel in order to improve its performance.
2. Precision hardware processing plant according to the appropriate heat treatment, can significantly improve the mechanical properties of steel, improve the service life of machine parts.
3. Heat treatment process can not only enhance the metal material to fully explore the performance potential of the material, reduce the net weight of the structure, save materials and energy, but also improve the quality of mechanical products and greatly improve the service life of machine parts.
4. Proper heat treatment process can remove various defects caused by casting, forging, welding and other heat treatment processes, refine the particles, remove loosening, reduce thermal stress, make the steel structure and performance more symmetrical.
