New sophisticated products in the field of precision engineering and optics require diamond tools of highest accuracies in combination with cutting edges that differ from the common spherical form. Within an industry driven research project, the Fraunhofer IPT has developed a novel diamond grinding and lapping machine to machine high precise diamond tools with spherical and - innovative - aspherical shapes. To achieve the proposed requirements of the diamond tools in terms of accuracy and shape, a machine design based on fundamental considerations of the axis configurations was realised [1,2]. Furthermore, the conduction of the grinding process was considered as well and influenced the design of the machine [3,4].
