Tumblers Effect on Nearby Machinery

[Crashmaster]

Does anybody know if a 1HP Vibratory Tumbler will have any ill effects on nearby
Machinery. Specifically a CNC Lathe and CNC VMC? I know this is probably a reach but I just want to be sure the vibrations aren't going to throw my machines out of whack. Thanks.

The effect will depend on how the machines are mounted and how stiff your floor is but I would say you will probably be able to detect a difference in finish quality if the tumbler is mounted close by. Depending on the parts it may be of no consequence (or could be a show stopper).

I suggest isolating the tumbler.

It's always best to isolate each piece of machinery, also. This is not usually financially practical, though.

Well crap, I was hoping that wouldn't be the replies I got. The tumbler would be bolted directly to the concrete floor, it that matters which I am guessing it doesn't.

Probably makes it worse. The vibrations from the tumbler will pass directly to the floor if it is directly bolted. Put it on isolation mounts.

A crude way of providing even more isolation than just attaching the tumbler itself to the floor with isolation mounts is to get a heavy steel plate and mount this to the floor on isolator mounts then mount the tumbler on this again with isolator mounts.

Thats not a bad idea at all, and from what I can remember (which isn't a lot) is that isolation mounts are pretty cheap.

And I am sure I have seen them advertised on CNCzone.

I'm sure vibratory mounts are a not bad idea but I highly doubt that a 1 HP tumbler is going to effect anything but a CMM.

That VMC your worried about is capable of creating some real vibrations.

I wouldn't worry about it myself.

Standard just my opinion disclaimers apply.

Because it runs at a constant speed for extended periods even a small vibratory device can create significant floor bounce if it happens to hit on a resonant frequency. Sort of like a mouse pushing an elephant on a swing, time the little pushes just right and the elephant gets a good ride.

VMC may create stronger vibrations but they are not as constant and often only short lived.

i would think a tumblers vibrations would definitely affect the accuracy of the machines ,
we ve had one job in particular where we needed to uphold bores on a bcd within a .0003 positional tolerance ,which proved to be dificult when the large mill on the other side of the floor was running the 4" shellmill (hogging), the vibrations threw things around some , not anything work worrying about under normal circumstances , but in tight times when even the machines own tolerances are trouble enough ,you don t need the extra headaches
