Re: [CAD_CAM_EDM_DRO] Re: Al Extrusion Vibration Damping

What about water under preasure?

You could increase stiffness by increasing air preasure (assuming it could be made air tight).

Water absorbs vibrations (at certain frequencies) converting them into waves inside the tank. Of
course resonance cuts two ways and could increase if the resonance frequencies match.
