Golf club groove configuration
View Patent ↗A golf club head, and a method of making the golf club head, with an improved striking surface. The grooves are formed in the strike surface with tight tolerances. The grooves may contain a plurality of portions, including a radiused or angled portion, a portion having substantially parallel walls, and a portion having a v-shape.
1. A method of making a golf club head, comprising:
providing a golf club head body having a flat metallic ball-striking face and a rough cut groove disposed therein, wherein the maximum depth distance of the rough cut groove is shorter than the overall distance of the rough cut groove;
providing a die having a projection and a plurality of texturing features; and
pressing the projection into the rough cut groove to displace material adjacent the groove to alter the rough cut groove into the final groove by pressing edge material of the rough cut groove into a final groove edge configuration at an interface between the ball-striking face and the groove, and pressing the texturing features into the face to form surface texturing, wherein the rough cut groove contains a longitudinal axis and the rough cut groove is radiused at toe and heel portions of the golf club head about axes of rotation that are perpendicular to the longitudinal axis and parallel to the face.
2. The method of claim 1 , further comprising machining the face so that it is substantially flat.
3. The method of claim 1 , wherein the step of pressing the projection into the rough cut groove includes displacing edge material at an interface between the rough cut groove and the face.
4. The method of claim 3 , wherein the edge material is displaced to form a radius.
5. The method of claim 3 , wherein the edge material is displaced to form a facet.
6. The method of claim 3 , wherein the edge material is displaced by the texturing features.
7. The method of claim 1 , wherein the step of pressing the projection into the rough cut groove includes displacing the material forming side walls of the rough cut groove to form a draft angle.
8. The method of claim 1 , wherein at least one texturing feature is provided on a projection.
9. A method of making a golf club head, comprising:
providing a golf club head body having a flat metallic ball-striking face;
forming a rough cut groove in the face;
providing a die having a projection and a plurality of texturing features; and
pressing the projection into the rough cut groove to displace material adjacent the groove to alter the rough cut groove into a final groove configuration by pressing edge material of the rough cut groove into a final groove edge configuration at an interface between the ball-striking face and the groove and pressing the texturing features into the face to form surface texturing,
wherein the step of forming a rough cut groove includes machining the rough cut groove into the face such that the rough cut groove has a maximum depth distance that is shorter than an overall distance of the rough cut groove, and wherein the step of forming a rough cut groove includes machining the rough cut groove into the face such that the rough cut groove contains a longitudinal axis and the rough cut groove is radiused at toe and heel portions of the golf club head about axes of rotation that are perpendicular to the longitudinal axis and parallel to the face.
10. The method of claim 9 , further comprising machining the face so that it is substantially flat.
11. The method of claim 9 , wherein the step of forming a rough cut groove includes spin milling the groove.
12. The method of claim 9 , wherein the step of pressing the projection into the rough cut groove includes displacing edge material at an interface between the rough cut groove and the face.
13. The method of claim 12 , wherein the edge material is displaced to form a radius.
14. The method of claim 12 , wherein the edge material is displaced to form a facet.
15. The method of claim 12 , wherein the edge material is displaced by the texturing features.
