本発明は、石材、建材等の研削、研磨等に用いられるポ
リッシャー用の複合砥石に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a composite grindstone for a polisher used for grinding, polishing, etc. of stones, building materials, etc.
従来、石材等の研磨、研削等に用いられるポリシャー用
の砥石としては、メタルボンドのステック状のものをポ
リシャーの中心から放射状に所定間隔を置いて取付けて
使用している。このような従来の砥石を用いて石材等の
研磨等を行う場合、ステック状の砥石の幅が小さいため
、砥石の間隔が広く、ワークの角が砥石間に入ってしま
い、砥石の研磨方向端部の欠は等が生じてしまう問題点
を有するものであった。BACKGROUND ART Conventionally, as grindstones for polishers used for polishing, grinding, etc. of stones, etc., metal bond stick-like grindstones are attached radially at predetermined intervals from the center of the polisher. When polishing stones, etc. using such conventional whetstones, the width of the stick-shaped whetstone is small, so the intervals between the whetstones are wide, and the corner of the work gets between the whetstones, causing the edge of the whetstone in the polishing direction to There was a problem in that parts were missing, etc.
これを防止するため、■砥石数を増す、■砥石幅を増す
、■砥石間隙を樹脂で埋める、等の対策が考えられてい
る。しかし、■および■の方法は砥石とワークとの接触
面積が増えるものの、コストアップ並びに研磨圧力ダウ
ンによる研磨力の悪化を伴い、実用的でない。In order to prevent this, countermeasures have been considered, such as: 1) increasing the number of grinding wheels, 2) increasing the width of the grinding wheels, and 2) filling the gap between the grinding wheels with resin. However, although methods (1) and (2) increase the contact area between the grindstone and the workpiece, they are not practical because they increase costs and deteriorate the polishing power due to a reduction in polishing pressure.
また、■の方法は角欠けは防止できるが、研磨圧力が低
下し、研磨力が不足する問題点を有し、研磨に時間がか
かり、といって圧力を上げると機械に無理がかかるもの
であった。In addition, although method (■) can prevent corner chipping, it has the problem that the polishing pressure decreases and the polishing power is insufficient, and polishing takes time, but increasing the pressure puts strain on the machine. there were.
そこで、ステック状の砥石をレジンで包んだ複合砥石が
考えられるが、このような砥石は研磨に際して、レジン
が早く減り、レジンで包んだ効果が少なく、また研磨圧
力が下がり研磨力が劣るという問題点を有する。Therefore, a composite whetstone in which a stick-shaped whetstone is wrapped in resin has been considered, but when polishing such a whetstone, the resin decreases quickly, the effect of wrapping with resin is small, and the polishing pressure decreases and the polishing power is inferior. Has a point.
本発明は格段に研磨力に優れ、欠は等が防止されて長寿
命を有するポリシャー用の複合砥石を提供することを目
的とするものである。An object of the present invention is to provide a composite whetstone for polishers which has excellent polishing power, is prevented from chipping, and has a long life.

粉が分散固化されたことを特徴とする。The composite grindstone of the present invention is attached to a polisher, and has grindstone pieces made of diamond abrasive grains or cubic boron nitride abrasive grains and metal powder embedded in the base, and diamond abrasive grains or cubic boron nitride abrasive grains and metal powder. It is characterized by the fact that grinding stone powder made of powder is dispersed and solidified.
本発明の他の態様による複合砥石は、砥石片が少なくと
も研磨方向端面に位置するよう構成される。A composite grindstone according to another aspect of the present invention is configured such that the grindstone pieces are located at least at the end face in the polishing direction.

。In the present invention as described above, the grindstone pieces are embedded in the resin base and the grindstone powder is dispersed and solidified, so the grindstone pieces ensure sufficient polishing power, the grindstone powder provides further polishing power, and at the same time These grinding stone pieces and grinding stone powder are firmly held in the resin base, and the width of the grinding wheel in the polishing direction is widened, which reduces the possibility of the corner of the workpiece entering the gap between the grinding wheels and causing corner chips of the grinding wheel. This prevents the surface pressure of the resin base from being worn out and the surface pressure decreases, and the dispersed and solidified grindstone powder protrudes and participates in the polishing, so the width of the grindstone piece can be reduced without impairing sharpness.
さらに、砥石片を少なくとも研磨方向端部に配置するこ
とにより、樹脂基地の片ベリが防止されるとともに研磨
力がより向上する。Furthermore, by arranging the grindstone pieces at least at the ends in the polishing direction, uneven burring of the resin base is prevented and the polishing power is further improved.
