Does Dynamat meet those requirements? @TonyDangerCoiro had some good experiences with it and it’s primarily intended for automotive applications which I imagine have similar requirements?
I get it but if you’re buying an industrial tool like say a Haas, you’re going to be sticking that in an area that’s prepared for it, like an industrial use zoned building. In that case, the noise it makes isn’t important, you can just have your workers wear hearing protection (which they probably needed in such an environment anyway).
Correct me if I’m wrong but Carbide 3D’s tools are deliberately targeted at smaller users who are as likely to be working from a spare room, classroom, office or garage as they are from an industrial workshop. For these people, the quieter you can get it, the more people can use it.
