A continuous-generation gear grinding method of conducting a gear grinding process such that while a thread-shaped grinding wheel is rotated around an axial center thereof and fed in an axial center direction, a position coming into contact with abrasive grains is constantly changed in the presence of a water-soluble grinding fluid by performing a grinding feed in a direction parallel to an axial center of a gear blank and by serially rotating the gear blank around the axial center, the grinding wheel being a vitrified grinding wheel having abrasive grains bonded by a vitrified bond with pores formed among the abrasive grains, and the abrasive grains having a grain size of F120 to F180.

Continuous-generation gear-wheel grinding method

A high emittance glass coating material which is applied to a surface of a specific structural body and fired on the surface, for providing on the surface a glass coating having a glass structure in which pigment particles having a predetermined degree of emissivity are dispersed, the high emittance glass coating material being characterized by including: a pigment covering film having a predetermined thickness, which is provided to cover each of the pigment particles, and which includes silicon dioxide (SiO ) such that a content of the silicon dioxide in the pigment covering film is higher than a content of the silicon dioxide in each portion of the glass structure which is adjacent to a corresponding one of the pigment particles.
