Abstract
A synthetic grindstone for performing surface processing includes: abrasive grains; a vitrified-material binder configured to retain the abrasive grains in a dispersed state; and a filler arranged in the binder in a dispersed state. The filler includes at least one of a first filler having an average grain size larger than an abrasive grain size of the abrasive grains, a second filler having an electrical conductivity, or a third filler having a hardness higher than a hardness of an object to be ground.
