  • Fixed abrasive grinding/polishing tool
    Publication number: 20050229499
    Abstract: A fixed abrasive grinding/polishing tool containing cerium oxide particles each being in the plate shape and having an average particle size in an in-plane direction of the plate-form particles of 10 nm to 200 nm, which are bonded together with a water-soluble polymer.

  • Mirror grinding method and glass lens
    Publication number: 20020019200
    Abstract: A mirror surface grinding method processes an optical glass material into a lens shape using a cup-shaped grinding stone. The grinding stone is pupplied with a polishing solution which contains charged fine particles, thereby electrically attaching the charged fine particles to the grinding stone. The grinding stone is rotated and moved relative to the optical glass material along a final shape to be generated from the optical glass material, thereby grinding an unnecessary portion of the optical glass material to remove it, using a peripheral face portion of the grinding stone, and at the same time polishing the final shape surface of the optical glass material using charged fine particles attached to an annular face portion of the rotating and moving grinding stone.
