CNC Turned Parts Of Heat Treatment

In order to improve the mechanical properties of the material and improve the machining performance of the material,The heat treatment processes should be used in the process of CNC turn machining. The arrangement of the heat treatment process depends on the material and heat treatment purpose.

 

(1) preparatory heat treatment

 

The purpose of preparatory heat treatment is to improve the machining performance of the parts,  it always using annealing, normalizing before CNC turning.

 

(2) elimination of residual stress heat treatment

 

The internal stress produced in the process of manufacturing and machining will cause the deformation of the work piece and affect the machining quality. Therefore, it is necessary to arrange the heat treatment,Heat treatment for eliminating residual stress is arranged after rough machining.

 

(3) final heat treatment

 

The ultimate purpose of heat treatment is to improve the strength, surface hardness and wear resistance of parts, it often arranged before the precision machining.
