Description

本発明は、銅張り・メッキ基板の研磨、プリント基板の穴埋めインク除去、バリ取り研磨、セラミック基板の研磨、ステンレス研磨、その他、非金属板等の研磨（研削を含む）に使用される回転砥石に関する。   The present invention relates to a rotating grindstone used for polishing a copper-clad / plated substrate, removing ink filling a printed board, deburring polishing, polishing a ceramic substrate, polishing stainless steel, and other non-metallic plates (including grinding). About.

前記のごとき各種の研磨には、従来、不織布ロール研磨材あるいは無端状ベルト研磨材が、被研磨材の材質及び研磨用途に合わせて使用されている。しかし、前記不織布ロール研磨材は、押圧研磨時あるいは高速回転研磨時に膨出変形等し易いなどの問題があり、また、無端状ベルト研磨材は、研磨材層が薄く、該研磨材の摩耗により研磨能力に変化が生じ易く、また、耐久性にも問題が残されていた。   Conventionally, in various kinds of polishing as described above, a nonwoven fabric roll abrasive or an endless belt abrasive is used according to the material of the material to be polished and the polishing application. However, the nonwoven fabric roll abrasive has problems such as being easily bulged and deformed at the time of pressure polishing or high-speed rotary polishing, and the endless belt abrasive has a thin abrasive layer and is worn by the abrasive. The polishing ability is likely to change, and there is still a problem with durability.

そこで、金属線で補強されたシート状の支持体と、弾性体と、多数の砥石片とよりなる筒状砥石が提供されている（特許文献１参照）。なお、前記金属線で補強されたシート状支持体は、遠心力による膨出変形を防止するものであり、結果として、幅の広い被研磨面を持つ物品の研削或いは研磨に好適であるとされている。
特開２００１―３１５０６４号公報 In view of this, a cylindrical grindstone made of a sheet-like support reinforced with a metal wire, an elastic body, and a large number of grindstone pieces is provided (see Patent Document 1). Note that the sheet-like support reinforced with the metal wire prevents bulging deformation due to centrifugal force, and as a result, is suitable for grinding or polishing an article having a wide surface to be polished. ing.
Japanese Patent Laid-Open No. 2001-315064

前記金属線の使用は、該金属線が円周方向に巻回されているため、遠心力による膨出変形を防止する効果が得られるが、金属線入りの特殊シートの準備が必要であり、重量が増すなどの問題、さらに砥石使用済み後の廃棄処理が面倒である等の問題が残されている。   Use of the metal wire, because the metal wire is wound in the circumferential direction, the effect of preventing bulging deformation due to centrifugal force is obtained, but the preparation of a special sheet containing the metal wire is necessary, There are still problems such as an increase in weight and a troublesome disposal process after using the grindstone.

That is, a fiber band material having excellent tensile strength is continuously wound spirally around the outer peripheral surface of the first elastic material layer. The fiber band material has a predetermined width in which fibers are woven in the vertical direction and the horizontal direction, and the outer peripheral surface of the first elastic material layer is uniformly clamped, and further, not only bulging deformation at high speed rotation, but also rotation The fibers in the length direction of the grindstone effectively prevent deformation in the width direction. Further, the weight of the product can be reduced, and after the grindstone is used, the fiber band material can be incinerated, can be easily disposed of, and can be provided at low cost.

前記本発明の実施の一形態は、前記繊維帯材を交互方向から螺旋状に連続巻回して２層としたことを特徴とする回転砥石である（請求項２）。この実施の一形態によれば、前記の本発明の作用効果に加えて、前記繊維帯材の強度が向上させられ、さらに一方向連続巻回の場合に生じ易い微妙な片寄りが防止される。   One embodiment of the present invention is a rotating grindstone in which the fiber band material is continuously wound spirally from alternate directions into two layers (Claim 2). According to this embodiment, in addition to the operational effects of the present invention described above, the strength of the fiber band material is improved, and subtle deviations that are likely to occur in one-way continuous winding are prevented. .

Specifically, the polyester fabric is impregnated with an impregnation treatment by adjusting the solid content of a phenol resin excellent in water resistance, heat resistance, and durability to a predetermined coating amount.

この実施の一形態によれば、必要とする引張強度とともに、好ましい耐水性、耐熱性、耐久性、さらには柔軟性を得ることができる。なお、ポリエステル織物に限らず、該ポリエステルと綿の混紡織物でもよく、また、含浸させる樹脂は、前記フェノール樹脂の変成品（ＰＶＡ、エポッキシ、合成ゴムにより変成）、その他、ＰＶＡ、合成ゴム、ウレタン等であってもよい。   According to this embodiment, preferable water resistance, heat resistance, durability, and flexibility can be obtained together with the required tensile strength. Not only polyester fabric but also polyester / cotton blended fabric may be used, and the resin to be impregnated is a modified product of the above phenol resin (modified by PVA, epoxy, synthetic rubber), other PVA, synthetic rubber, urethane Etc.

以下、添付図面を参照して、本発明を実施するための最良の形態について説明
する。図１は、本発明に係る回転砥石の一部斜視図、図２は、図１の縦断面図、図３は、繊維帯材の巻回状態を示す斜視図、図４は、繊維帯材の２層巻き状態を示す斜視図である。 The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. 1 is a partial perspective view of a rotating grindstone according to the present invention, FIG. 2 is a longitudinal sectional view of FIG. 1, FIG. 3 is a perspective view showing a winding state of a fiber band material, and FIG. 4 is a fiber band material. It is a perspective view which shows the two-layer winding state.

図中、１はベークライト等からなる円筒芯材であり、該円筒芯材１の外周面には、多孔性材のスポンジからなる第１弾性材層２が形成される。該第１弾性材層２は、例えば、ポリエチレン、ポリウレタン、合成ゴム等の多孔性材によって形成される。   In the figure, reference numeral 1 denotes a cylindrical core material made of bakelite or the like, and a first elastic material layer 2 made of a porous sponge is formed on the outer peripheral surface of the cylindrical core material 1. The first elastic material layer 2 is formed of a porous material such as polyethylene, polyurethane, or synthetic rubber.

つぎに図３に示すように、前記第１弾性材層２の外周面に引張強度に優れた繊維帯材３が螺旋状に連続巻回される。該繊維帯材３は、ポリエステル織物にフェノール樹脂を含浸処理してなり、一実施例では、その引張強度は１８０ｋｇｆ／２５ｍｍであった。   Next, as shown in FIG. 3, the fiber band material 3 excellent in tensile strength is continuously wound spirally around the outer peripheral surface of the first elastic material layer 2. The fiber band 3 was obtained by impregnating a polyester fabric with a phenol resin, and in one example, the tensile strength was 180 kgf / 25 mm.

なお、図面実施の一例では、前記螺旋状に連続巻回した繊維帯材３の外周面に、図４に示すように、連続巻回方向を逆にして同様の繊維帯材３ａが連続巻回され、該繊維帯材３、３ａが２層に形成されている。   In the example of the drawings, the same fiber band 3a is continuously wound on the outer peripheral surface of the spirally wound fiber strip 3 as shown in FIG. 4 with the continuous winding direction reversed. The fiber strips 3, 3a are formed in two layers.

さらに、前記２層に連続巻回された繊維帯材３、３ａの外周面に、第２弾性材層４が形成される。該第２弾性材層４、４ａは、適宜用途に応じた弾性を有するゴムシートであり、図面実施の一形態では、前記繊維帯材と同様に２層に形成され、前記繊維帯材３、３ａの上面を押え付けて一体化されている。もっとも、前記第２弾性材層４は１層であってもよい。   Further, the second elastic material layer 4 is formed on the outer peripheral surface of the fiber strips 3 and 3a continuously wound around the two layers. The second elastic material layers 4, 4 a are rubber sheets having elasticity according to the use as appropriate. In one embodiment of the drawings, the second elastic material layers 4, 4 a are formed in two layers like the fiber band material, and the fiber band material 3, The upper surface of 3a is pressed and integrated. However, the second elastic material layer 4 may be a single layer.

つぎに、前記第２弾性材層４ａの外周面に砥石５が碁盤の目状に配置される。なお、前記碁盤の目状に配置される砥石５は、回転縦横方向に対して整列させられることなく、それぞれの横列が回転方向に対して所定の角度となるように固着される。   Next, the grindstone 5 is arranged in a grid pattern on the outer peripheral surface of the second elastic material layer 4a. The grindstones 5 arranged in a grid pattern are fixed so that each row is at a predetermined angle with respect to the rotation direction without being aligned with respect to the rotation vertical and horizontal directions.

前記砥石５の固着は、円筒状に形成された第２弾性材層４の外周に固着する場合には手数を要する。したがって、前記第２弾性材層４が展開された状態で前記砥石５を接着剤により固着し、その後、前記繊維帯材３ａ外周に巻回することにより行われる。なお、前記砥石５は、各種合成樹脂と各種公知の砥粒を成形して構成してなる。   The fixing of the grindstone 5 requires a lot of work when it is fixed to the outer periphery of the second elastic material layer 4 formed in a cylindrical shape. Therefore, the grinding stone 5 is fixed with an adhesive in a state where the second elastic material layer 4 is unfolded, and then wound around the outer periphery of the fiber band material 3a. The grindstone 5 is formed by molding various synthetic resins and various known abrasive grains.
