Regarding the issue of chrome plating allowance
Thread Content
Please discuss the issue of leaving a margin for chrome plating. For example, a sleeve is 40 in length, and the outer circle and inner hole drawings require dimensions of Φ35-0.01 and Φ10+0.01 respectively. The technical requirements are chrome plating D·YCr10 and heat treatment to reach a hardness of HRC58-62. What should its process flow be like?

I think it should be like this: Carry out heat treatment after leaving a margin, then grind the outer circle and inner hole to Φ35-0.01 -0.02, Φ10 +0.02 +0.01, then D·YCr20, and finally grind to the drawing size Φ35-0.01, Φ10+0.01.
