N2 - Infrared aspherical lens are widely applied in automobile, civil aviation, and space industries. The normal processing method for infrared aspherical lens is traditional polishing with low efficiency, or diamond cutting with intense wear of tools when processing large sized lens. Therefore, the ultra-precision diamond grinding technology of large sized infrared aspherical lens was researched to improve processing efficiency and surface quality. In this paper, the key technologies of grinding large sized infrared aspherical lens was investigated, including on-machine precision truing of arc-shaped diamond wheels technology, errors analysis and compensation technology for high form accuracy, and grinding parameters optimization technology for homogeneous and well surface morphology. With these technologies, multispectral CVD zinc sulphide for aspherical lens with diameter of 93.5 mm was ground with form error PV≤0.8 μm and roughness Ra <5 nm. This research gives an indication of the strategy to follow to achieve high efficiency and quality ground aspheric surfaces on brittle infrared materials.
