I have a few 6"Ø parts with a lot coming out of the ID. I"m not having very good insert life and was looking for some recommendations. Also I'm not finding a way to break the chip very well. Which is especially a problem with my boring bar since it is not a thru hole. Near the bottom of the boring cycle the chips sometimes get crunched up and its a cringe worthy sound.
Any help with speeds,feeds, DOC, and maybe inserts would be greatly appreciated.
Material is 304
Using a positive rake insert on boring bar, Sandvik insert grade 2025. .015 rad
OD tool is negative rake Sandvik insert grade 1125
