Hello,

I just caught a signal with 1x to 30x rpm harmonics on a spindle. This is the first time I see that. I suspect that the spindle housing is loosened in its fit (this is a cartridge spindle). Have someone already seen this before?

Thanks for your help,

Answer to myself or anyone else...

It appeared that the spindle was vibrating in its cartridge. The play was probably over 0.010'' creating 1x...to 30x rpm harmonics.
