My CNC Cincinnati Hawk 150 started to make a big noise/vibration while
Part-off. I make the machine turn counterclockwise with the tool
upside down. Somebody told me the problem could be (this is only a
possibility) the ways are worn because it's not a normal/good practice
to use the CNC that way for Part-off.

What do you think about ?
Has somebody had this problem?
What do you suggest, changing the ways is a very expensive test to do,
I have a small machine shop and I need this machine for my biggest
customer.

Thanks very much

On my 10" manual lathe the quickest cure for vibration when parting is
reducing spindle speed.
