Golf club groove configuration
View Patent ↗The present invention is directed to a golf club head with an improved striking surface. The grooves are machined into the strike surface with tight tolerances using a profiled cutter.
1. A method of making a golf club head, comprising:
providing a golf club head body having a face; and
machining a plurality of grooves into the face using a profiled cutter having a turning axis that is parallel to the face,
wherein the profiled cutter is shaped to create an edge radius in a groove-to-face junction between at least one of the plurality of grooves and the face.
2. The method of claim 1 , wherein the edge radius is between about 0.005 inch and about 0.012 inch.
3. The method of claim 1 , wherein at least one of the plurality of grooves is radiused at toe and heel portions of the golf club head about axes of rotation that are perpendicular to a longitudinal axis of the groove.
4. The method of claim 1 , further comprising machining the face so that it is substantially flat.
5. The method of claim 1 , further comprising roughening the face.
6. A method of making a golf club head, comprising:
providing a golf club head body having a face; and
machining a groove into the face using a profiled cutter that is configured to create an edge feature in a groove-to-face junction between the groove and the face,
wherein the edge feature is an edge radius.
7. The method of claim 6 , wherein the edge radius is between about 0.005 and about 0.012 inch.
8. The method of claim 6 , wherein the groove is radiused at toe and heel portions of the golf club head about axes of rotation that are perpendicular to a longitudinal axis of the groove.
9. The method of claim 6 , further comprising machining the face so that it is substantially flat.
10. The method of claim 6 , further comprising roughening the face.
11. A method of making a golf club head, comprising:
providing a golf club head body having a face; and
machining a groove into the face using a profiled cutter that is configured to create an edge radius in a groove-to-face junction between the groove and the face, wherein the groove has a width that is less than 0.045 inch and the profiled cutter has a turning axis that is parallel to the face.
12. The method of claim 11 , wherein the edge radius is between about 0.005 and about 0.012 inch.
13. The method of claim 11 , wherein the groove is radiused at toe and heel portions of the golf club head about axes of rotation that are perpendicular to a longitudinal axis of the groove.
