Abstract:
A method of making a golf club head comprising:forming a golf club body by casting a molten material chosen from the group consisting of titanium and alloys of titanium in a mold and allowing said molten material to solidify, once solidified, said golf club body comprising a hollow body having a face portion, a top wall, a side wall and a heel portion adapted to receive a golf club shaft, said face portion having a front surface and a rear surface, said face portion further comprising an alpha case and an underlying base material; attaching a sole plate to said golf club body to form an assembled club comprising a hollow golf club head defining an outer surface and an inner surface, said sole plate including a weight member located on an inner surface thereof, said weight member having a center of gravity located beneath the center of gravity of said golf club body; and removing said alpha case from said golf club body by exposing said golf club body to a conformal milling process capable of selectively removing said alpha case such that a sufficient quantity of said alpha case is removed from said face portion so as to expose said underlying base material.
