Provided is a continuous-generation gear-wheel grinding method with which it is possible to produce highly accurate gear wheels with high efficiency by using a high-porosity vitrified grindstone and a water-soluble grinding fluid in continuous-generation gear-wheel grinding. This method uses: a vitrified grindstone (12) made by bonding abrasive grains with a vitrified bond in a state where pores are formed among the abrasive grains, wherein the grain size of the abrasive grains is from F120 to F180; and a water-soluble grinding fluid (GF) including a surfactant that improves cleaning performance and an extreme pressure additive that improves lubricity. Thus, the wearing of the vitrified grindstone (12) is reduced in continuous-generation gear-wheel grinding, and therefore, the dressing interval is extended, grinding interruption time is shortened, and grinding work efficiency is improved, and thus, it is possible to produce highly accurate gear wheels with high efficiency. |
