I am not personally familiar with your Grizzly mill, but have first hand experience with their large drill press. In my case, the noise and slight vibration was from a belt that had a heavy spot in it where it was joined. The belt looked and felt fine, but watching it run at top rpm showed a shake in it. A replacement US made belt eliminated the problem totally, and may be the same problem you are experiencing.

Hi Bob, I am new to the site and therefore not familiar with all the policys. I felt the responses that were suggested addressed the problem to my satisfaction. Seeing that there was an option provided to close the thread I clicked on it.I did not know the thread was supposed to run indefinetly.I guess I know better now.

The Grizzly is a geared configuration, The problem appears to have been a resonance issue. I have been working the mill the last 2 days and have had no issues.Works great with 1/2'' endmill in low range.
