Abstract: Disclosed is a device for machining panels, in particular panels made of derived timber products, in and essentially horizontal position. The device has a sawing and/or milling jig with at least one saw blade and/or at least on milling cutter. The device is preferably fitted with a combined sawing/milling jig whose movements are controlled by computer using several parameters. The device can also have a preferably computer-controlled panel-holding rig, a suction device for removing machining residues, such as chips and dust, means for conveying the panel and/or cutouts out of the device following machining or means for lifting the machined panel.
