摘要：A cup-shaped grindstone for grinding an end face of an annular portion of awork to form tooth grooves in the end face includes a grinding portion provided aroundan outer periphery of a disk portion. Abrasive grains of CBN are electrodeposited oneach of first, second and third grinding faces of the grinding portion. Cooling-liquid

ejecting bores are provided in a lower end of the first grinding face. To form the toothgrooves, the following steps are carried out: a rough-finish processing step cuts thetooth grooves by intermittently feeding the cup-shaped grindstone in a predeterminedamount at a time, and a finish processing step of finishing the tooth grooves by retainingthe cup-shaped grindstone at a predetermined position after the rough-finish processingstep. During both steps, a cooling liquid is supplied from cooling-liquid ejecting boresdefined in the first grinding faces of the cup-shaped grindstone.
