摘要： A polishing brush (4) includes a grinding element bundle (9) formed with a plurality of wire-shaped grinding elements (28) formed by impregnating and solidifying an assembly of inorganic filaments with resin, and a grinding element holder (7) having a holding hole (20) holding the base end portion of the grinding element bundle 9 on an outer peripheral side surface (7c) serving as a grinding element-holding surface. The grinding element bundle (9) has a front surface (9a) facing forward in a rotational direction (R1) and a back surface (9b) facing backward. The grinding element bundle (9) is held in the grinding element holder (7) such that the front surface (9a) and the back surface (9b) are inclined in the same direction relative to a virtual surface (30) that includes a center point (P) of a cross section (9d) of the grinding element bundle (9) cut across an outer peripheral side surface (7c) and the axis of center of rotation (L) of the grinding element holder (7) and extends in a radial direction. The wire-shaped grinding elements (28) included in the grinding element bundle (9) are easily displaced and can release excessive force applied thereto.

摘要： A wheel brush (1) includes a grinding element bundle holder (3) having an annular grinding element bundle-holding surface (12) that faces the outer circumferential side and a plurality of grinding element bundles (4) that are formed by gathering a plurality of wire-shaped grinding elements (5). The grinding element bundle-holding surface (12) has a plurality of holding holes (16) arrayed in a circumferential direction (R), the grinding element bundles (4) protrude to the outer circumferential side from the grinding element bundle-holding surface (12) while one end portions are inserted into the holding holes (16). First protrusions (18) protruding to the outer circumferential direction are provided on first opening edge portions (17a) adjacent to the holding holes 16 at a first direction (L1) side in the rotational center line direction orthogonal to the circumferential direction R (R) in opening edges of the holding holes (16) in the grinding element bundle-holding surface (12). The first protrusions (18) are continuous in the circumferential direction R (R) to configure an annular first flange portion (19).

摘要： A rotating tool includes a tool body including a polishing tool and a shank, and a flange part provided in the tool body. The polishing tool includes a plurality of linear grinding members and a grinding member holder to hold the linear grinding members. The flange part is an annular member, and attached to the grinding member holder, so as to be movable in the direction of an axial line and rotatable about the axial line. When the inner circumferential surface of a hole formed in a workpiece is processed, the grinding member holder and the annular member are inserted into the hole. When run-out on the front side of the rotating tool occurs, the annular member comes into contact with the peripheral wall surface of the hole, whereby the run-out of the tool body is reduced.

摘要： A polishing brush (1) includes a brush-shaped grindstone (12) holding grinding element bundles (11) of wire-shaped grinding elements (27) in an annular shape and a grinding element displacement-restricting member (13) for restricting displacement of the grinding element bundles (11) outward. The brush-shaped grindstone (12) has a grinding element holder (15) holding the base end portions (upper end portions) of the grinding element bundles (11). The grinding element displacement-restricting member (13) has an annular part (33) surrounding the wire-shaped grinding elements (27) from the outer peripheral side at a position between the tip ends of the wire-shaped grinding elements (27) and the grinding element holder (15) in the direction of the axis of center of rotation (L) and at a distance away from the tip ends of the wire-shaped grinding elements (27) and the grinding element holder (15). Since the portions on the side closer to the grinding element holder (15) of the grinding element bundles (11) held in the grinding element holder (15) are exposed outward, cutting fluid or air supplied from the outer peripheral side of the polishing brush (1) easily reaches the polished portion of a workpiece.

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.
