The approximately vertical, rectangular base frame (10) of the machine surrounds a supporting grid (14) with clamping members (16) for the plate-like workpieces (8). A support (40) can be moved over the supporting grid along two opposite frame sides (12), and a carriage (45) is movable on the support (40), which carriage (45) has a machining unit (50), the at least one tool spindle of which is directed with the tool axis towards the supporting grid (14). The feed and positioning of the machining unit (50) are effected by means of fine-thread feed spindles, fastened in a fixed position and so as to be locked against rotation, and allocated spindle nuts which can be driven in a rotary manner. The latter are mounted in one feed device each with a numerically controlled feed motor. One feed spindle each is fastened on the two frame sides (12), and the associated feed devices are each connected via extension arms (42) to an end of the support (40); the relevant feed motors are synchronously controlled. A third feed spindle is fastened on the support (40), and the associated feed device is connected to the carriage (45); spindle and feed device are located inside the support, which is designed as a hollow section. The machine offers diverse and accurate machining possibilities, in particular milling and drilling operations. …<IMAGE>… |
