We studied and tested porous vitrified-bonded diamond wheel with super fine grains (0-1/8μm). Polishing and lapping were currently employed in finishing process. There are some problems in worker's circumstance and abrasive grain cost, because a lot of free abrasive grains are used. We try to make grinding stones of super fine diamond abrasive that displace polishing and lapping grains. The pores faired chip exhaust and grinding lubricant flow. They provide pores by mixing pore agent in stone. The superfinishing process checked grinding performance of these grinding stones. The grinding performance of these stones is clarified for different bonds, pore agents and abrasive grains. We obtained superfinishing surface of nanometer-scale at Ra.
