Abstract
A method of manufacturing a rolling bearing ring includes preparing a coil material and a press machine for obtaining a rolling bearing ring from the coil material, setting the coil material on the press machine, and obtaining the rolling bearing ring by heating the coil material on the press machine to a temperature not lower than an A1 transformation point, thereafter punching a part of the coil material into a ring form, and thereafter quenching a formed object on the press machine.
