A device is provided for machining rod-shaped workpieces such as window profiles or door profiles which can be moved on at least one horizontal plane by means of a transport device. A machining device with tools is provided on a plane that is substantially perpendicular to the movement direction of the workpieces, the machining device being spatially aligned with the workpiece on the perpendicular plane. The machining device includes partial circle segments which are arranged on perpendicular planes that can be adjusted relative to one another and on the partial circle arc of which the tools are arranged in a movable manner. Each of the individual partial circle segments can be moved in the X, Y, and Z direction.
