Hi everyone.
I am having trouble getting a good finish when turning 1018. Part is 1.25" dia by 9.25" long. Turning down to .75 " 8.5" long. I am having slow way down to get a chatter free cut resulting in a crap finish.
I found a few threads related to my problem, and people said to use a positive insert. So my question is, do they mean an insert with a more positive chip break or a positive rake tool holder.
I am currently using a MCLNR with a CNMG431MP. This works great for 1018 when part is robust and can keep the speed up.Thanks for any advice/help you guys can muster.
Jesse
