GRINDSTONE FOR CORRECTING A SURFACE PLATE, FOR PRODUCING A WORKPIECE OF HIGH SURFACE ROUGHNESS BY IMPRINTING THE FINE SURFACE OF A SURFACE PLATE, AND A CORRECTING METHOD THEREOF

摘要

PURPOSE: A grindstone for correcting a surface plate, for producing a workpiece of high surface roughness by imprinting the fine surface of a surface plate, and a correcting method thereof are provided to secure grinding power by maintaining the grain of a stone with a particle-shaped open graphite hole.;CONSTITUTION: A grindstone for correcting of a surface plate comprises a surface plate correcting carrier(10), a correcting grindstone(12), and a soft polishing material. The surface plate correcting carrier is arranged on a polishing table(1). The surface plate correcting carrier has a hole(11) for holding the correcting grindstone. The correcting grindstone is maintained in the holding part of the carrier. The polishing device supplies the correcting grindstone to the polishing table to polish. The correcting grindstone is formed in a fan shape on a circular central part.;COPYRIGHT KIPO 2010
