PROBLEM TO BE SOLVED: To reduce the cost for manufacturing a rolling bearing ring such as an inner ring, which in turns a rolling bearing comprising this rolling bearing ring, by improving efficiency in machining of a raceway surface of an inner ring raceway 16 or the like. SOLUTION: After hardening a part as a raceway surface by heating, grinding by a lathe using a cutting tool 18 is performed to the hardened part so as to form a raceway surface. Since machining corresponding to the quantity of a part to be ground can be performed without waste, the manufacturing cost can be reduced. COPYRIGHT: (C)2009,JPO&INPIT
