Abstract

This invention provides a golf club head processing method of performing blast processing on a face surface on which a scoreline is formed. The processing method according to this invention includes the steps of filling the scoreline with a masking material before the blast processing, and removing the masking material from the scoreline after the blast processing.

Claims

1. A golf club head processing method of performing blast processing on a face surface on which a scoreline is formed, comprising the steps of:

filling the scoreline with a masking material before the blast processing; and

removing the masking material from the scoreline after the blast processing.

2. The method according to claim 1, wherein the masking material includes wax.

3. The method according to claim 1, wherein a roughness of the face surface after the blast processing corresponds to an arithmetic average roughness of 0.5 μ

m (inclusive) to 4.0 μ

m (inclusive).

4. A golf club head having undergone a processing method defined in claim 1.

5. A golf club head having undergone blast processing on a face surface thereof on which a scoreline is formed, wherein

an edge of the scoreline has a trace of the blast processing, while an inner wall of the scoreline has no trace of the blast processing.
