ヤスリ、ダイヤモンド砥石等の電着式砥石に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electroplated grindstone, such as a diamond file or a diamond grindstone, used for processing such as internal grinding and external grinding of a workpiece made of a hard material.
従来より硬質材料よりなる被加工部材の内、外
研削には、スチールブランクを用いた電着式砥石
が広く使用されている。 Conventionally, electrodeposited grindstones using steel blanks have been widely used for internal and external grinding of workpieces made of hard materials.
このスチールブランクの電着式砥石は製造が容
易であるため、一般的に使われているが、１mm以
下の小径の穴をあける場合又は仕上加工長さが長
い場合には、ブランク自体にゆがみが生じ穴の径
が長さ方向で一定しないという欠点があつた。 This steel blank electrodeposited grinding wheel is commonly used because it is easy to manufacture, but when drilling holes with a small diameter of 1 mm or less or when the finishing length is long, the blank itself may become distorted. There was a drawback that the diameter of the resulting hole was not constant in the length direction.

案されている。 In order to overcome the drawbacks of the electrodeposited grindstone using a steel blank, an electrodeposition grindstone using a cemented carbide blank made of tungsten carbide or the like has been proposed.

ツキ層との密着性がそれらの性質上極めて悪いた
め、電着式砥石の使用中における砥粒の剥離が大
変多かつた。 When an electrodeposited grindstone using this carbide blank is used for finishing small-diameter holes, etc., the blank itself hardly distorts. Since the adhesion with the plating layer is extremely poor due to their nature, the abrasive grains often peel off during use of the electrodeposited grindstone.

て極めて砥粒の剥離が多く、電着式砥石の寿命を
縮めていた。 In particular, the plating layer of an electrodeposition type grindstone is considerably thicker than a normal plating layer, so thermal expansion or internal stress distortion of the plating layer occurs, and the abrasive grains are easily peeled off. When a carbide blank is used, combined with the poor adhesion between the carbide and the plating layer, the abrasive grains often peel off, shortening the life of the electrodeposited grindstone.
このように従来の電着式砥石は、その働きを充
分に発揮しないまま廃棄しなければならないもの
が多く、また品質も不均一になり、経済上及び生
産効率上好ましいものではなかつた。 As described above, many of the conventional electrodeposited grindstones have to be discarded without fully demonstrating their function, and their quality is also uneven, which is not desirable from an economic and production efficiency standpoint.

Furthermore, by coating with titanium titanium oxide, it is possible to tell whether or not titanium oxide treatment has been performed, and this electrodeposited grindstone can be manufactured without mistakes. Furthermore, when drilling holes, the reflective properties of titanium oxide make positioning with respect to the workpiece easier.
