I have been building a few parts on my lathe. I recently had a 10.03mm shaft around 100mm long that needed to be reduced in size by 0.03mm. I used a DCMT 070402 (NX2525 grade) insert running around 640rpm with a slow feed. Instead of cutting it rubbed in part. The end result was half OK (somewhat nice finish - but not uniform in size), but left me wanting for a better solution. I assume that the 04 nose radius was a bit much? I am thinking of trying out a DCMT cutter with an 02 radius to see if that helps.
About half way through the cut it started screeching like a pig. Not sure why that would happen. Possibly deflection and rubbing due to lack of DOC.
What do you generally use for really light fluff cuts in steel?
