Loose-abrasive machining with ceria slurry is traditionally employed for finishing optical glasses. The machining process, however, has problems relating to detrimental impact on environment caused by the usage of slurry and low form accuracy due to the usage of soft polishing pad. Therefore, it is strongly recommended that the process be replaced with fixed-abrasive machining, but conventional fixed-abrasive tools have serious problem of low finishing efficiency. In this study, a structured-controlled, that is, a spiral-structured pad having fixed-abrasive layer and abrasive holding layer is introduced for finishing optical glasses to overcome the above-mentioned problem. A series of experiments revealed that the good surface quality was comparable to that obtained by conventional polishing with ceria slurry and polishing pad and the finishing efficiency was much higher. Furthermore, it was found that the edge roll off of workpiece could be significantly improved.
