POLISHING METHOD, BRUSH-LIKE GRINDING STONE, POLISHING BRUSH, AND LINEAR MEMBER AGGREGATE

摘要

A brush-like grinding stone (3) in a polishing brush (1) includes a brush holder (6) and a linear member aggregate (7) detachably held in the brush holder (6). The linear member aggregate (7) includes a large number of bundles (51) of the linear members (50) obtained by hardening aggregated yarn of inorganic filaments impregnated with a resin, and a brush holder (70) holding ends of the bundles (51). A linear member holder (70) in the linear member aggregate (7) is detachably attached to each of a plurality of holding holes (68) that is open in one side in an axial line direction L. In a case where any of the linear member aggregates has a failure, such as breakage, only the failed linear member aggregate needs to be replaced. Thus, it is not necessary to discard the entire brush-like grinding stone. Consequently, the polishing cost can be reduced.

1. A polishing method using a brush-like grinding stone including a bundle of linear members and a brush holder that holds the bundle, the polishing method comprising:
preparing the brush-like grinding stone by fixing an end of the bundle to a linear member holder to prepare a linear member aggregate and detachably attaching the linear member holder to each of a plurality of holding holes on the brush holder that is open in one side in an axial line direction; and performing polishing after at least one of attaching and removing the linear member aggregate to and from the brush holder when the linear member aggregate held on the brush holder needs to be reduced, added, or replaced before performing the polishing.
