A cylindrical, abrasive grinding wheel (10) having a cylindrical abrasive region (12) with an abrasive surface (18) at an outer circular band thereof. The abrasive region includes layers (26) of abrasive particles. The layers (26) of abrasive particles can be tilted with respect to an axis of rotation (23) of the grinding wheel or they can be arranged such that grooving in the grinding wheel and a workpiece ground by the grinding wheel can be reduced. Alternatively, the abrasive region can be formed from a plurality of abrasive segments each having layers of abrasive particles. The layers of abrasive particles can be staggered in the direction of the axis of rotation from one segment to another. This can also reduce grooving in the grinding wheel and workpieces.

L'invention concerne une meule abrasive cylindrique (10) possédant une zone abrasive cylindrique (12) avec une surface abrasive (18) et une bande circulaire extérieure. La zone abrasive comprend des couches de particules abrasives (26). Les couches de particules abrasives (26) peuvent être inclinées par rapport à l'axe de rotation (23) de la meule ou disposées de manière à réduire le rainurage de la meule et de la pièce usinée. En variante, la zone abrasive peut être formée à partir de segments abrasifs dont chacun possède des couches de particules abrasives. Les couches de particules abrasives peuvent être décalées en direction de l'axe de rotation d'un segment à l'autre, ce qui permet également de réduire le rainurage de la meule et de la pièce usinée.
