@robryk@social.wuatek.is It's mostly two things. 1: To avoid the table to act as a resonant chamber with the wood surface and the small space below it. 2: High frequencies don't like massive things, and milling at 13krpm is gonna generate noise in said range, adding "as much weight" as possible within realistic times, will always help. Note I said "mass damper" and not "tuned mass damper", the second one would be calculated for specific frequencies, as you suggest.
