ABSTRACT:
A vibration damping structure for a machine tool is provided. The structure includes first and second plate members disposed in an opposing spaced apart relationship with one another. A cast structure formed of a polymer concrete extends between the first and second plate members. A first structure is attached to the first plate member and extends inwardly of the cast structure. The first structure has a compression surface extending in a spaced apart relationship from the surface of the first plate member. A second structure is attached to the second plate member and extends inwardly of the cast structure. The second structure has a compression surface extending in a spaced apart relationship from the surface of the second plate member and in an opposed spaced apart interlocking relationship with the compression surface of the first structure so that tensile forces applied to the first and second plate members will correspondingly produce compression forces between the opposing compression surfaces and the damping material therebetween.
