Abstract
A method for manufacturing a golf club head comprises a step of preparing a head main body having a plane forming a ball striking face; a step of forming, in the plane, a primary groove having a groove depth exceeding the upper limit depth specified by the Rules of Golf; and a step of surface-trimming the plane to obtain a secondary groove having a groove depth complying with the Rules of Golf while maintaining the shape of the groove bottom of the primary groove, wherein the surface treatment is a blasting treatment in which abrasive materials are collided against the plane.
Claims15
A method for manufacturing a golf club head, comprising:
- a preparation step of preparing a head main body having a plane forming a striking face for striking the ball;
- a formation step of forming, in the plane, at least one primary groove extending in a toe-heel direction, and having a groove depth larger than the upper limit depth specified by the Rules of Golf;
- and
- a surface trimming step of surface-trimming the plane to reduce the groove depth of the primary groove while maintaining the shape of at least the bottom of the primary groove so as to obtain the primary groove as a secondary groove having a groove depth complying with the Rules of Golf, wherein the surface-trimming is a blasting treatment process in which abrasive materials are collided against the plane, whereby the striking face with a groove is formed by the surface-trimmed plane with the secondary groove.
