I have a job that calls for some stepped diameter dowel pins. The pins are standard McMaster 316 Stainless.
Our lathe is a HAAS ST-30 with an S30 style collet chuck. I only need a handful of parts (10). I will be taking a 0.250" diameter pin down to 0.245" over a portion of the length. I do not have surface grinding capabilities in house. Lathe tooling available would be a CNMG-431, or a DNMG-331, or a Top Notch grooving tool such as NG2094L (Kennametal 2599767).
Since the depth of cut is drastically smaller than the tool nose radius of any of my current tooling, the whole issue of work-hardening the stainless comes to mind. Another other option is to undersize the hole in the part and find a source of undersized dowel pins. Any suggestions on that? Google didn't pop anything up in the first page or two.
Just looking for input on this so I don't underestimate this little sideshow of a part. I'm pretty new at all this so your guidance is appreciated.
Thanks, Daen
