Summary:PROBLEM TO BE SOLVED: To provide technique capable of improving productivity when an outer groove is formed on a hardened steel member.SOLUTION: As shown in FIG.(b), a cutting groove 81a formed by a primary cutting is formed on a shaft 81. And, a super hard milling cutter 70 which is rotating comes close to the shaft 81 as a white arrow and cuts into the cutting groove 81a. Because conventional rough grinder processing and finish grinder processing are performed by only single cutting, productivity is improved.
