I'm getting chatter when boring a circle. Mostly 10 oclock to 2 oclock and 4 oclock to 8 oclock. A solid guess would be the x axis? I know i have roughly .0008" backlash on the Y axis and a bit more on the x, but the majority of the vibration feels like it's in the head.
Is this typical of spindle bearings going bad - or would i get chatter everywhere if that were happening?
Also a side question:
When i'm in DNC and i have to either feed hold or stop the spindle, is there a way to restart or even continue the program? It seems as though when i do this i have to reboot the machine to get it to do anything besides jog. It won't even do an MDI move.
Thanks,
Ryan
