  • Centerless grinder
    Patent number: 4194323
    Abstract: The grinding wheel of a centerless grinder comprises a cylindrical abrasive grinding surface sandwiched between two slightly frustoconical guide surfaces made of a resilient material. The regulating wheel has a surface that mates with the composite surface of the grinding wheel. This arrangement permits blanks of a brittle material fed axially of the wheel to be ground to a barrel shape without chipping.
