Abstract: The invention relates to a device (1) for processing the surface of objects (3) and comprises a predetermined number of processing stations (B1-B8) performing processing processes and a conveying unit performing processing movements. The objects are transported into predetermined desired positions at the processing stations (B1-B8) by means of the conveying unit. The device (1) further comprises a central controller (7), by means of which the processing movements of the conveying unit and the processing processes of the processing stations are synchronized by presetting a clock pulse being correlated with the processing movement of the object (3) to be processed and controlling the respective processing process via the central controller (7) for each processing station (B1-B8).
