Abstract

A machine for machining workpieces, especially metal sheets, comprises a machining device, a main drive and an auxiliary drive which is different therefrom. Both drives serve to generate a relative movement between the machining device and a workpiece for the purpose of machining the workpiece, wherein the machining device is movable relative to the workpiece and/or the workpiece is movable relative to the machining device with a main movement by means of the main drive and wherein the machining device is movable relative to the workpiece with an auxiliary movement by means of the auxiliary drive. A machine with high adaptability to different machining tasks is provided if, for the machining device, an adjusting drive is provided which is different from the main drive and by means of which the machining device can be positioned within an adjustment region into different initial positions, starting from which the machining device is movable as necessary with an auxiliary movement by means of the auxiliary drive. A method of machining workpieces comprises corresponding method steps.
