    Inconel 625 on CNC Swiss

    Does anyone have suggestions as what Sandvik grade would work well on AMS5666 (Inconel 625) for cut off and turning? I am having the cutoff insert chipping on the 5th part first chips on the bar stock side of inset then the next chipped on the part/pickoff side? this is with the speeds and feeds the Sandvik reps gave me of 160SFM and Feedrate of .002 per rev. Hope someone has something that works well.Thanks

    Your SFM seems alright. I'd start with .0005 IPR. I usually max out at about .0009 IPR when cutting off SS or High Temps. Try Sandvik Grade 1105. I personally use Iscar cutoff inserts. Grade IC907, 908, or IC806 and they work great. Good luck.

    We have been using Mitsubishi on Inco 718 with great success.
