The spindle bearings in my Hardinge DV-59 went south about a week ago. It
started out as a real faint growl. As the hours went by, the growl got
louder. By the end of the second day, I couldn't run it above 1500 RPM for
more than 5 minutes or the noise was too hard to take . I had to get a job
done so I pushed it but I'd work on them way before they get that noisy. Try
running your machine for a few more hours/ days. If you did do damage, it
will become painfully apparent.
