Heat Treating Chamfered Parts: Before or After Makes a Difference

“For years, I have always told people who ask me that my machines pretty much don’t care if a part is hard or soft,” says James Richards of James Engineering.
In a simple experiment, Richards ran several parts through multiple machining and finishing processes to determine whether the hardness or softness of certain steel alloys had any effect on chamfering. What he found regarding hardness or softness did not surprise him. What he did note were the different outcomes that resulted from heat treating the part before or after chamfering.
“We have yet to find a material that we cannot create a chamfer and/or edge finish on. As to whether we chamfer before or after heat-treating—that’s a very different story.” ~ James Richards
This week’s Technical Tuesday highlights Richards’ article “Chamfering: Hard vs Soft Parts and Before vs After Heat Treating”, which appeared in the July 2019 issue of Gear Technology.
