Claims (4)

外周に砥石層が形成されており、前記砥石層の外周面と工作物との接触面に向けて研削液を供給しながら前記工作物を研削加工する砥石において、
前記砥石層の内周面に砥石円周方向に対して所定の角度傾斜し、等間隔に複数の傾斜溝が刻設され、
前記傾斜溝と前記接触面の砥石円周方向と平行な一方の縁の延長線との交点を一方交点、他方の縁の延長線との交点を他方交点と定義した場合、一の傾斜溝の他方交点と、一の傾斜溝と隣接する傾斜溝の一方交点とが砥石円周方向において所定のオーバラップ量だけオーバラップし、
前記砥石層の摩耗により前記傾斜溝が前記砥石層の外周面に出現したとき、前記接触面の砥石円周方向長さが前記オーバラップ量よりも小さくなるように、前記工作物に対する前記砥石の切込み量と、前記傾斜溝の傾斜角度及び間隔との少なくとも一方が設定されていることを特徴とする砥石。 In the grindstone for grinding the workpiece while supplying a grinding liquid toward the contact surface between the outer circumferential surface of the grindstone layer and the workpiece, a grindstone layer is formed on the outer periphery,
The inner circumferential surface of the grinding wheel layer is inclined at a predetermined angle with respect to the grinding wheel circumferential direction , and a plurality of inclined grooves are engraved at equal intervals.
When the intersection of the inclined groove and the extension line of one edge parallel to the grinding wheel circumferential direction of the contact surface is defined as one intersection point and the intersection point of the other edge extension line is defined as the other intersection point, The other intersection and the one intersection of one inclined groove and the adjacent inclined groove overlap by a predetermined overlap amount in the grinding wheel circumferential direction ,
When the inclined grooves appear on the outer peripheral surface of the grindstone layer due to wear of the grindstone layer, the grindstone circumferential length of the contact surface is smaller than the overlap amount of the grindstone with respect to the workpiece. A grindstone characterized in that at least one of a cutting depth and an inclination angle or interval of the inclined groove is set . 請求項１に記載の砥石において、前記砥石層の外周面と前記工作物との接触面内であって、前記砥石層を円周上の任意の位置で砥石軸と平行に、且つ、砥石径の方向に切断したときの当該切断線上に存在する前記傾斜溝の幅の和が常に等しいことを特徴とする砥石。 The grindstone according to claim 1 , wherein the grindstone layer is in a contact surface between the outer peripheral surface of the grindstone layer and the workpiece, and the grindstone layer is parallel to the grindstone axis at an arbitrary position on the circumference and the grindstone diameter. A whetstone characterized in that the sum of the widths of the inclined grooves existing on the cutting line when cutting in the direction of is always equal. 請求項１又は２に記載の砥石において、前記砥石層の内周面側から外周面側に向かって溝幅が徐々に縮小する傾斜溝が刻設されていることを特徴とする砥石。 The grindstone according to claim 1 or 2 , wherein an inclined groove whose groove width is gradually reduced from the inner peripheral surface side to the outer peripheral surface side of the grindstone layer is formed. 請求項１又は２に記載の砥石において、前記砥石層の内周面側からの溝深さが異なる複数の傾斜溝が刻設されていることを特徴とする砥石。 The grindstone according to claim 1 or 2 , wherein a plurality of inclined grooves having different groove depths from the inner peripheral surface side of the grindstone layer are formed.
