ABSTRACT:
The generally vertical, rectangular base frame (10) of the machine surrounds a support grate (14) with attachment members for the flat work pieces (8). A carrier (40) is moveable along two oppositely disposed frame sides (12) over the support grate, and a carriage (45) is moveable on the carrier (40), the carriage (45) carrying a work mechanism (50) equipped with at least one work tool spindle with its work tool axis directed toward the support grate (14). Feeding or positioning of the work mechanism (50) is accomplished by means of fixed and non-rotatably attached finely threaded feed spindles and associated rotatably drivable spindle nuts. The spindle nuts are each part of an associated feed device with a numerically controlled feed motor. Each of the feed spindles is attached to an associated one of the two frame sides (12) and the associated feed device is connected with one end of the carrier (40) through a bracket (42), the involved feed motors being synchronously controlled. A third feed spindle is attached to the carrier (40) and the associated feed device is connected with the carrier (45), the spindle and the feed device being located inside of the hollow profile of the carrier. The machine offers numerous and exact machining applications, especially milling and drilling operations.
