An engineer approached me today with a project requiring rework of a 3.500/3.501 counterbore that is finished to size but needs to have the surface finish increased from 20 to 63 to 125 Ra. I'm not sure this can be done without ID knurling it and then boring it back to size. Anyone have any thoughts on this?
