    摘要: A manufacturing apparatus, of a grinding stone which is manufactured by attaching abrasive grains respectively having polyhedral shapes in which mutually opposed surfaces are parallel to each other to a base member, is provided with: an abrasive grains classifying apparatus adapted to classify the abrasive grains based on sizes of the abrasive grains defined by face-to-face distances between the mutually opposed surfaces; and an attaching apparatus adapted to attach the abrasive grains classified by the abrasive grains classifying apparatus to the base member. The attaching apparatus is provided with: a template which is disposed above the base member to be movable with respect to the base member and formed with a guide hole through which the classified abrasive grains pass; a vibration generator connected to the template or the base member and adapted to apply a vibration to the abrasive grains passing through the template; and an electrolytic deposition bath adapted to electrolytic deposit the abrasive grains passing through the template.
