Abstract

The base (1) of a heavy machine tool is mounted on a foundation block (2), which has a number of hemi-spherical cavities (2') which are interconnected by channels (9) and lined with an airtight lining (3). The mouths of the cavities are sealed with collars (4) of elastomeric material which fit in recesses in the base (1). A non-return valve (6) allows the air to be exhausted from the cavities (2') and maintain a vacuum which provides a large holding down force for the machine tool. The elastomeric collars (4) act as anti-vibration mountings and prevent the transmission of vibrations through the ground to other machines which could adversely affect their operation.
