I’ve got some hardened D2 steel parts that need to be as nice as I can possibly make them. This is part of an assembly and I can’t send it out for grinding.
The part is similar to a collet, where I need to face the top and profile the outside (it’s not round so it can’t be done in a lathe). The flatness of the top needs to be as good as possible, and the profile of the outside needs to be fricking tight. No hard tolerances, just as good as possible.
I remember when I toured the haas factory a couple years ago they were using a flymill with a single cbn insert to mill surfaces flat within a Few tenths. So my original thought was to copy that with a sandvik cbn facemill to make the flat and then use a nice endmill to profile the outside.
But.... i would really like to use a single indexable endmill with a
single cbn insert to both profile and make the flat with one tool. Anybody done anything similar or can recommend any tools that fit the bill? I’m a newbie to tool steel so I may be way off base, if so let me know any other ideas (my generation thinks “billet aerospace aluminum” is the secret sauce to every damn part, so its rare I do anything else).
