The machine just doesn't quite sound right at all RPMs. It just becomes more noticeable as you get above 6000 RPM or so. It gets better as it runs longer (or maybe my ears just become more accustomed to it). |
I have a feeling for what you mean. Definitely the noise varies with speed which I think is a resonance and definitely your ears are not a reliable detector because they do habituate.
All you can do is get the tech in to check it out; if the machine is under warranty this is what they should do whenever you ask. Although maybe I have a bit of extra clout with my Haas dealer having bought seventeen machines and asked for a quote on number eighteen

today.
I mentioned the Super Mini that was noisy; I have a new VF2 that is still under warranty and some mornings it makes a really funny noise during Warm Up. It seems to be temperature dependent and does not happen every day. My plan is to monitor it very closely when the machine is about two months away from the end of the warranty and if it is still doing it get the dealer in to start looking at things.
