Abstract: In a frame with a horizontal bed (10) and a vertical upright (12) there is for bracing and stiffening a vertical rigid wall (14) rigidly with the bed (10) and the upright (12) connected. The bed (10), the upright (12) and the wall (14) are cast as a single piece of a polymerizable resin-concrete. The wall (14) provides the frame with a high bend and torsional stiffness at a low weight. The wall (14) additionally serves to receive guides and bearing arrangements for functional elements of the machine tool, which by this means can be disposed spatially one above the other.
