| Outline of Final Research Achievements |
The superfinishing with the new vitrified bonded mechanochemical/ mechanochemical hard abrasive stones has been applied to the super-planarization of hard materials for a wafer like glass, sapphire and so on,
In the super-planarization of glass, the machining time of the superfinishing has been one-fifth of that of conventional polishing. On the other hand, in that of sapphire as super hard material, the machining time of the multistage superfinishing has been one-forth of that of conventional lapping. Moreover, this superfinishing has achieved the surface roughness of 2.0 nmRa.
