Abstract

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.

First claim

What is claimed is:

1. A method of making a golf club head, comprising:
providing a golf club head body having a metallic face;
milling a plurality of elongate grooves in the face, wherein the grooves extend between a heel portion of the body and a toe portion of the body, wherein the grooves have a longitudinal axis and at least one groove is curved at toe and heel ends about axes of rotation that are perpendicular to the longitudinal axis so that a length of a maximum depth portion of the at least one groove is shorter than the overall length of the groove;
pressing a die into the metallic face of the golf club head body to displace material of the face, wherein the die includes a plurality of projections including a plurality of texturing features, and wherein pressing the texturing features into the face forms surface texturing between adjacent grooves in the metallic face.

2. The method of claim 1 , further comprising a step of machining the face so that it is substantially flat.

3. The method of claim 2 , wherein the step of machining the face includes fly cutting the face.

4. The method of claim 1 , wherein the groove intersects the surface of the face at an edge, and wherein pressing the die into the face displaces material disposed at the edge.

5. The method of claim 4 , wherein the edge material is displaced by the texturing features.
