Hey everyone, One of my first posts but long time lurker
in 10+years machining, Ive never felt so defeated.
I am running a small cnc lathe, trying to bore 1-3" diameters.
I have a few 100 programs that ive been running for 5+ years on this machine with these boring bars, perfect finish and sizes.
we hired a new machinist who thought he could save time on my programs so he set the start point to a finished diameter on a 3.5" stock and a 1.5" diameter. so upon finishing the cycle *smash into the piece.
okay, so we aligned the machined with some professionals and all the tool heights are dead on,turret realigned... but unless my boring bars are less than 2" off the turret they vibrate like crazy, 1" thick bars 4-5" deep at the most..
I have tried everything to figure this out and i cant stop the vibration, super slow rpm with heavy cuts, super fast rpm with small cuts, nothing works...
any help would be appreciated sorry for the sloppy post im really busy now that i have to repair these bores on the conventional lathe
