Greetings!
I run a Haas ST10 CNC lathe, and I'm cutting a steel numbered 4340. I am told this steel is pretty hard since it is used for tooling. The problem I am facing is that I can only rough cut somewhere around .005" per pass @ around 400-500 rpm; anything deeper and/or faster, the frickin' machine starts vibrating excessively. The round stock I use usually doesn't exceed 1"-2" in diameter, although sometimes it can.
My current synopsis is that this machine stinks overall, and it wasn't made for cutting harder metals like 4340.
-or-
I may be using the wrong kind of insert.
If at all possible, I would like to take deeper cuts at faster speeds on this machine. Below is a link to an insert I am considering:
DNMG432 MF2 TH1 Grade Carbide Turning 372172 - MSC
Would an insert like that be better? The current insert I'm using is not designated for the hardest metal(s); the one I'm considering (see link) is rated to cut the hardest metal(s), according to Seco.
Thank you for reading!
