PURPOSE:To provide excellent abrasion resistance and fracture resistance strength so as to improve surface roughness of a machined surface by fixing plural pillar monocrystal diamonds on a grinding working face of a wheel at the equal height in the predetermined arrangement pattern while respectively arranging their crystal orientations in the equal direction. CONSTITUTION:As the crystal orientations of plural pillar monocrystal diamond chips 4 buried in the circumferential face of a cylindrical wheel 1 are arranged in the equal direction, any crystalline grain on a grinding working face 1A is abraded uniformly, so that truing work is required at only the first time. When an interval and a projection amount of the diamond chips 4 are increased, a clearance between the chips 4, in other words, a chip pocket can be increased, so that dressing work can be greatly reduced. On the other hand, the projection amount of the chip pocket 4 is minimized, and the chips 4 are arranged in the crystal orientations having strong strength against the grinding direction, so that the crystalline grains are hardly fractured fragilely during the action, and abrasive grains hardly fall off as the abrasive grains are uniformly held, and consequently, deterioration in the surface roughness can be prevented.
