My 8520 came home this weekend. Couldn't be more excited. There's some minor work to do on it still but it's in great shape. Just started my first cut and I'm getting this terrible noise. It's so loud...to the point where I may need hearing protection. I'm using a 1/4" HSS endmill cutting about 1/8" down onto aluminum. Speed is at 1900 RPM. It seems that the faster I move on the X the noise lessens but this can't be normal....
