In order to solve the above-mentioned problems, this invention uses an abrasive sheet material having a large number of radially separated pieces that are connected by a connecting part in the center, and the connecting part becomes the tip surface, and the parts are gathered together and adjacent to each other. The polishing sheet is bent with the polishing surface facing up so that the cut-off pieces with lapped edges become the peripheral wall surface, and the cut-off pieces are fixed with an adhesive so as to maintain the gathered state.
例えばハンドグラインダのチヤツクでシヤフト
を支持し、そして凹入部等を研磨する。
For example, the shaft is supported by the chuck of a hand grinder, and recesses and the like are ground.
図において、１は片面に研磨面を有する研磨シ
ートである。
In the figure, 1 is a polishing sheet having a polishing surface on one side.
上記の研磨シート１は、中央の連結部２と、こ
の連結部２によりそれぞれ連結された多数枚の放
射状切離し片３とによつて構成されている。 The polishing sheet 1 described above is composed of a central connecting portion 2 and a large number of radial cut-off pieces 3 connected to each other by the connecting portion 2.
次に上記研磨シート１を用いて研磨材Ａを製造
する方法を説明する。 Next, a method for manufacturing the abrasive material A using the abrasive sheet 1 will be explained.
連結部２が先端面となり、かつ寄せ集めて隣接
縁をラツプさせた切離し片３が周壁面となるよう
研磨面を表面にして研磨シート１をコーン状に屈
曲したのち、切離し片３の寄せ集め状態を維持す
ると共に、寄せ集まつた切離し片３の内側にシヤ
フト４の先端を嵌入して接着剤５を介し固着す
る。 After bending the abrasive sheet 1 into a cone shape with the polishing surface facing up so that the connecting portion 2 becomes the tip surface and the cut-off pieces 3, which are gathered together and the adjacent edges are wrapped, become the peripheral wall surface, the cut-off pieces 3 are gathered together. While maintaining the state, the tip of the shaft 4 is inserted into the inside of the gathered separation pieces 3 and fixed with the adhesive 5.
なお、各切離し片３の研磨材Ａの回転方向反対
側縁部を図示のように接着しない遊離状態として
おくことにより緩衝性があつて研磨作業時に大き
な衝突音が発生したりする不都合をなくすること
ができる。 In addition, by leaving the edge of each separated piece 3 on the side opposite to the rotating direction of the abrasive material A in a free state without bonding as shown in the figure, a buffering property is provided, thereby eliminating the inconvenience of generating a large collision sound during the polishing operation. be able to.
また、切離し片３は、第４図で示したように研

ることができる。 The cut-off pieces 3 can be provided by providing radial slits 6 in the polishing sheet 1 as shown in FIG. 4, or by providing radially arranged cutouts 7 in the polishing sheet 1 as shown in FIG. If the above-mentioned cut-off 7 is provided, each cut-off piece 3
The overlapping thickness of the two can be reduced and the diameter can be made smaller.
なお、図示省略してあるが、帽子状の研磨材を
成型し、そしてシヤフトの先端ゴム等の弾性部材
の外側に研磨材を被せて支持させる交換方式であ
つてもよい。 Although not shown, a replacement method may be used in which a cap-shaped abrasive material is molded and the abrasive material is placed on the outside of an elastic member such as rubber at the tip of the shaft and supported.
以上のように、この考案に係る研磨材によれ

成型体の表面に砥材を付着させるようなコストの
上昇原因となる問題を解消することができる。
As described above, since the abrasive material according to this invention is manufactured using an abrasive sheet, it is possible to solve the problem of attaching the abrasive material to the surface of the cone-shaped molded body, which causes an increase in cost. can.
また、砥材を付着させてある場合目詰りにより
短時間で研磨力が低下するが、各切離し片の研磨
縁砥材の切れ味が悪くなり、そして脱落すると次
の砥材によつて研磨するので、常に切れ味のよい
研磨が可能になり、長期間使用することができ
る。 In addition, if abrasive material is attached, the polishing power will decrease in a short time due to clogging, but the sharpness of the abrasive material on the polishing edge of each cut-off piece will become dull, and if it falls off, it will be polished by the next abrasive material. This enables sharp polishing at all times and can be used for a long period of time.
