Loose-abrasive machining with ceria, zirconia or iron oxide slurry is traditionally employed for finishing optical glass. The machining process, however, has problems involving inefficiency and a detrimental impact on environment. Therefore, it is strongly recommended that the process be replaced with fixed-abrasive machining, but conventional fixed-abrasive tools have problems relating to low finishing efficiency or low finished surface quality. In this study, a lapping film utilizing agglomerative fine abrasives is introduced for finishing optical glass to overcome the above problems. The finishing experiments revealed that the good surface quality was comparable to that obtained by polishing with ceria slurry and the finishing efficiency was much higher. Furthermore, it was found that in the process of finishing, agglomerative abrasives were worn flat uniformly and gradually, that is, the self-dressing action of agglomerative abrasive occurred continuously.
