heat treatment for CNC Machining parts

Why do you need heat treatment during machining?

At our CNC Machining shop, Many machined parts  require heat treatment, mainly for the following purposes:
A. Eliminate the casting stress of the material, the purpose is to obtain more stable processing size and precision;
B. Improve the cutting performance of the parts, the purpose of which is to process more efficiently, process quality and processing cost in the process of parts processing;
C. Improve the rigidity, hardness and wear resistance of the parts.
