Problems with heat treatment
Thread Content
Today, the workshop leaders are discussing an issue. Regarding the decision on the processing technique for the valve body, should the heat treatment of the valve body be carried out after its rough machining, or should heat treatment take place first and then rough machining? Should heat treatment be done first followed by rough machining? Should I finish the rough machining first and then carry out the heat treatment?
This problem has existed in the past: after rough machining, some parts would be sent to external heat treatment facilities, and they would deform after heat treatment.
I don’t understand; it seems that heat treatment should be carried out first, followed by precision machining.
It needs to be deformed. . . Therefore, for finishing, reheat treatment should be considered. During heat treatment, reinforcement should be applied to reduce deformation.
I understand now; in our factory, parts are first subjected to heat treatment before machining
It depends on what kind of heat treatment is used; those that result in minimal deformation can be carried out after the rough machining stage
