The objective of this investigation is to clarify a new and high efficient mirror machining process with using ultrasonic and low frequent vibrations, that has been named "superposition superfinishing (SSF process)". In the first report, it was confirmed that a stock removal rate of superposition vibration cutting as cutting process on this SSF process can be higher than that of low frequent superfinishing, and that a high efficient mirror machining can be practically achieved. In the second report, by analysis and consideration on superposition cutting track, it was found that cutting length of this superposition vibration cutting strongly influence on a stock removal amount. In this report, as one reason of obtaining a high stock removal rate, we have adopt equivalent grade characteristics of ultrasonically vibrated abrasive stone. It has be shown that the grade of abrasive stone decreases according as amplitude incleases. On the result of some experiments, it is found that this phenomenon can be controlled by an amplitude value of ultrasonic vibration, and that a rate of abrasive stone ware per one meter of superposition superfinishing is lower than that of low frequent superfinishing in the case of large maximum cross angle.
