12. Heat Treatment of Precision Turned parts

Heat treatments can be applied on precision CNC turned parts to improve their key properties such as hardness. 

Heat treatment can be applied to metal parts throughout the manufacturing process. 

– Hardening: used to harden the material and make it stronger, also decreases the ductility. 

– Annealing: heats metal parts to a very high temperature and then slowly cools to achieve the desired microstructure. 

– Normalizing: used to relieve internal stresses that were created during machining service. 

– Quenching: heating the metal to a very high temperature, followed by a rapid cooling step.
