AI Technical Summary

Technical Problem

The existing metal wood club heads have a large tolerance in the precision curvature and rotation control of the face, resulting in large variations between club heads, and small spray heads have shortcomings in club flight trajectory and rotation control.

Method used

By using grinding techniques on the ball hitting surface of the club head to generate grinding patterns in a variety of different directions and textures, a complex surface texture is formed to control the contact force and rotation characteristics of the club and the ball.

Benefits of technology

By precisely controlling the face curvature and rotation characteristics of the club head, the variation between the club heads is reduced, and the flight distance and rotation control ability of the club are improved.

Abstract

To provide a metal wood golf club having a milled ball striking surface, and a set of golf clubs having milled faces.SOLUTION: A wood-style golf club head includes a strike face and a body that cooperate to define a hollow internal club head volume. The strike face is formed from a strike plate having an outer perimeter, and a frame surrounding the strike plate. The strike plate is affixed to the frame across the entire outer perimeter. The strike plate and the frame define a continuous ball striking surface that has a surface texture characteristic of milling that extends continuously across both the strike plate and the frame.SELECTED DRAWING: None
