Nanometric grinding technologies have been developed for fabricating axisymmetric and aspherical mould inserts of cemented tungsten carbide for optical/photonic uses. In this work, a process for truing and dressing ultrafine diamond wheels for nanometric grinding, including the wheel evaluation techniques, was successfully developed. This enabled the achievement of a grain pack density of 87% for the wheels with a mesh size of 3000. A compensation method was proposed to minimise the effect of the initial wheel dimensional and profile errors through the integration of a ‘dummy’ grinding procedure to the grinding process. With the developed grinding protocol, cemented tungsten carbide aspherical mould inserts of 6 and 1 mm in diameters with profile accuracies of ~0.4 μηι in PV value and average surface roughness of below 10 nm were fabricated after only one actual grinding cycle.
