Abstract: Optical glass is widely applied in aerospace, photoelectricity, space technology, precision engineering and other fields.Requirements on surface quality of optical glass are getting higher and higher.In this paper, grinding optical glasses with large abrasive eletroplated diamond wheel is researched, including the influence of grinding parameters on surface quality of optical glass from two aspects of grinding force and surface morphology.In addition, the research progress of two kinds of machining methods, namely ultrasonic grinding and compression molding, are reviewed and the future development trend of optical glasses processing has been predicted.
