发明名称 Golfing iron club and manufacturing method thereof
摘要 A manufacturing method for a golfing iron club and an iron golf club manufactured by the method. A shaft is connected to a head 1 having a face 3 on a front and a shaft attachment portion on one side. After a pre-forging stage using an upper die and a lower die, a rear region corresponding section 9'A and a lower peripheral face corresponding section 11A are machined with an end mill A. Then post-forging is performed using an upper die and a lower die to form the head 1. Thereafter, post-machining is performed using an end mill B. Thus, a rear region 9A and a lower peripheral face 11 can be formed without forging. Machining can be carried out between the pre-forging and post-forging stages, so that locations which are difficult to forge can be accurately formed. In addition, the head 1 is able to be formed more freely, owing to a post-machining stage.
