    摘要: A cup-shaped grindstone (18) for grinding an end face of an annular portion (3) of a work (W) to form tooth grooves (4) in the end face includes a grinding portion (21) provided around an outer periphery of a disk portion. Abrasive grains of CBN are electrodeposited on each of first (21a), second (21b) and third (21c) grinding faces of the grinding portion. Cooling-liquid ejecting bores (21d) are provided in a lower end of the first grinding face (21a). To form the tooth grooves (4), the following steps are carried out: a rough-finish processing step cuts the tooth grooves (4) by intermittently feeding the cup-shaped grindstone (18) in a predetermined amount at a time, and a finish processing step of finishing the tooth grooves (4) by retaining the cup-shaped grindstone (18) at a predetermined position after the rough-finish processing step. During both steps, a cooling liquid is supplied from cooling-liquid ejecting bores (21d) defined in the first grinding faces (21a) of the cup-shaped grindstone (18).
