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.
Claims8
A frame for a machine tool work station, comprising:
- a horizontal bed;
- at least one vertical upright attached to the bed;
- a head stock movably disposed on said horizontal bed;
- a means on the upright for securing a workpiece;
- a vertical, substantially quadrilateral wall for bracing extending between said at least one upright and said bed, said wall rigidly connected with said at least one upright and with said bed, said wall extending longitudinally from said upright and substantially to a side of the bed away from said upright;
- a mounting unit disposed on said wall, said mounting unit being (a) a guideway adapted for slidably receiving functional elements of the machining work station or (b) a mounting element for receiving functional elements and/or machine elements of the machining station, said mounting unit being disposed above the space necessary for sliding travel of the headstock parallel to said vertical wall;
- wherein said vertical wall, said vertical upright, and said bed are cast as a single piece of a polymerizable resin-concrete comprising mineral particles bound by a setting polymer resin.
