The machine tool has a stand (4) displaced along one coordinate axis relative to an elongate machine bed (1), provided with a tripod unit displaced in 2 further coordinate directions having a pivoted machining spindle (13), with a plate-shaped workpiece holder (30,31) pivoted between a horizontal rest position and a vertical working position. The tripod unit has a central support tube (10) for the machining spindle, supported by a universal bearing (9) from the stand and 3 telescopic props (14,15,16) spaced by 120 degrees, similarly supported by universal bearings (21,22,23). |
