geof's idea works pretty good.
but you should still be able to chamfer mill the part in a decent cnc mill I have done if for years. indexable is the best way to go and you really need to have the largest shank size avail. cause if your running a 1/2 or smaller shank size and trying to get a .250 depth it wont fly.
also shorten up that tool in the holder to were it is just sticking out enough to do the job.
BTW what kinda mill and taper holders as this make a huge dfference in the rigidty, you may have to take less of a cut ie more pass's
in all honesty if its just a chamfer I wouldnt waste mill time I would use a large emergency collet and put them in the lathe it takes a whopping 5-10 seconds at best. if you dont have a collet nose for your lathe and only a chuck then a mill would be faster. |
