ABSTRACT:
A half toroidal CVT disk having an inner surface portion, an outer surface portion and a toroidal surface having a given machining allowance is centered with said inner surface portion worked prior to the heat treatment of said half toroidal CVT disk as the standard thereof, and then is chucked by a chuck mechanism. The toroidal surface of the chucked half toroidal CVT disk is ground by a grinding mechanism with the grinding wheel for grinding the half toroidal CVT disk in a state that one of said half toroidal CVT disk and said tool is inclined at a given angle with respect to the other.
