I've had numerous issues turning parts with 01 oil hardened drill rod, on my CNC machines.
I use 36" lengths- import, 9/16" and 11/16" in diameter.
The problem has been the hardness varying from stock piece to piece in the 9/16".
If it's as normal it machines beautifully and accurately from part to part.
But some of it is so hard it tears up my inserts, produces a lousy finish and jumps around in size from part to part. That is the extreme and thankfully, haven't gotten any that bad lately.
What I'm finding now is 1/2 of my stock coming in is good, but then the other half produces and acceptable finish, but it will not hold tolerance from part to part, and shortens insert life.
This has only been with the 9/16" stock. The 11/16" is fine.
I'm at my wit's end trying to come up with a solution. I've tried slowing down my feed and depth of cut.
It's going to effect my business with the lack of availability and then 1/2 of it having this issue when it gets here. I don't know what to do.
Any suggestions on trying to get this hard 01 to work would be much appreciated.
