The guide part is mounted on the fixation part. The guide block includes at least two drives for adjusting the position of the guide part relative to the fixation part, so that the position of the guide part relative to the fixation part can be adjusted in at least two degrees of freedom. The fixation part of the guide block includes a housing which is hollow, and the drives are located inside the housing.
