I have placed thick 1" thick soft rubber tiles in whole my workshop to dampen noise and prevent damage when I drop some thing (end mill). The tables for the mill and 2 lathes are placed on these rubber tiles. The tables are also fixed to the wall by using a thick rubber fixture. I haven't noticed any change on the mill or mini (0.5 kW 60kg) lathe. The small lathe (1.5 kW 260kg) is noticeably more resonating when turning unbalanced workpieces using the 4 claw chuck. This has however no influence on the parts turned. It works for me, so give it a try.
