Surface machining device

A surface machining device, comprising

• a substrate support for receiving a substrate to be machined, the substrate support comprising a circulating conveyor belt for receiving the substrate, the conveyor belt having a corresponding movement direction parallel to the movement direction of a first gantry drive,
• a machining unit which can be adjusted relative to the substrate support along a first and a second movement axis, the movement axes essentially running orthogonal to one another and the machining unit being adjustable at least along the first movement axis by means of the first gantry drive,
• a position detector sensor for ascertaining an orientation of a substrate on the substrate support and
• a control unit for controlling the movement of the machining unit depending on the orientation of the substrate on the substrate support, wherein synchronization of the circulating conveyor belt and the first gantry drive is effected by the control unit,
• wherein the machining unit comprises one or more inkjet print heads which are housed in a print head receiving unit and the machining unit is configured to pivot relative to the substrate support about a height axis which extends perpendicularly to a plane formed by the first and second movement axes, whereby the pivoting is performed by a pivoting drive to the print head receiving unit.

• wherein the machining unit is configured to pivot relative to the substrate support about a height axis which extends perpendicularly to a plane formed by the first and second movement axes;
• wherein the substrate support comprises a circulating conveyor belt for receiving the substrate, wherein the conveyor belt is pivotable about the height axis, so that the substrate can be twisted into an optimum position relative to a print head, and wherein synchronization of the circulating conveyor belt and the first gantry drive is effected by the control unit such that the machining unit is guided sufficiently parallel to a straight edge of the substrate to allow for realization of respectively parallel lines without grid steps.
