Abstract
Provided are a golf club head and a method for producing the golf club head. The golf club head comprises a striking face that in turn comprises a recurrent texture pattern that has a period T and that is defined by a plurality of depressions, each depression having an average depth no greater than 0.10 mm. The striking face also comprises a plurality of scorelines that at least partially intersect the recurrent texture pattern and that have a scoreline pitch Ps such that T/Ps is greater than 1.0, each scoreline having an average depth no less than 0.10 mm.
Claims20
A method of manufacturing a golf club head comprising the steps of:
- on a golf club head body comprising a striking face, a sole portion, and a top portion opposite the sole portion, the striking face comprising a generally planar surface, surface milling the striking face by advancing a cutter in an advancement direction, being a direction from the sole portion toward the top portion, across the striking face at a feed rate that cyclically varies, resulting in a recurrent texture pattern that is a plurality of variably-structured depressions that, in combination, form a characteristic and repeating elemental sequence having a period T, the period T being defined as a length of the elemental sequence measured in the advancement direction of the cutter;
- and
- forming a plurality of scorelines,
- wherein, the scorelines are at least partially coextensive with the recurrent texture pattern, the scorelines define a scoreline pitch Ps such that T/Ps is greater than 1.0, and each of the scorelines has an average depth no less than 0.10 mm.

- and
- forming a plurality of scorelines,
- wherein:
- the scorelines are at least partially coextensive with the recurrent texture pattern and define a scoreline pitch Ps such that a first ratio, T/(N*Ps), is between 0.85 and 1.15, N being a whole number greater than 1;
- and
- each scoreline has an average depth no less than 0.10 mm.
