Using a Citizen Lathe L20, on one machine(same program) F.0015, Spindle Speed 6000, leaves a burr on the finished part size. Steel, 1/4" Diameter.
Neutral insert, right hand holder,but what I am having a hard time figuring out is why on one machine it is smooth and no issues, but on the other machine it is having problems.
I have tried changing the core, and offsets in the Y axis for the cutoff tool for centering, and it has not appeared to help.
Looking for suggestions, as when I tried to use an insert to turn off this burr, burr rides up on top of insert, causing it to remain.
