Hi fellow machinists!!!
I am currently working on an Edward´s 5 cyl radial engine and I have to machine a small groove in hardened material (For the conrod pins). The plan is to use ground hardened shafting material and the problem is that it´s case hardened to 62HRC
I can sharpen a carbide piece to the exact geometry, but I am not sure it will work for machining 62HRC material.
My other option is to grind the groove, but I would prefer not to choose this option as the groove will end up being a U shape instead a square bottom.
Any suggestion?
Thank you all!
