Golf club head and method of manufacturing the same

Abstract

An aim of the invention is to provide a golf club head with high dimension precision at a reticle edge and a comfortable ball hitting feeling, and a manufacturing method thereof. For obtaining the purpose, the golf club head is manufactured through the following steps: forming a first coating layer (6) with higher hardness partially on at least a club surface (2) of a club head substrate (5), then performing notching treatment for forming the retile (3), and then forming a second coating layer (7) which has smaller thickness and lower hardness. Preferably, surface cutting is performed for the club surface of the club head substrate (5) for obtaining a preset flatness according to the invention. Nickle coating layer, or chromium coating layer, etc. is better for the first plating layer (6), and copper coating layer is better for the second coating layer.

Description

technical field [0001] The invention relates to a golf club head and a manufacturing method thereof, in particular to an iron golf club head and a manufacturing method thereof. Background technique [0002] In iron golf club heads, grooves called score lines are formed on the club face. In addition, in order to increase the hardness of the club face or to improve corrosion resistance and aesthetic appearance, a plating layer is generally formed on at least the club face. [0003] In the prior art, when manufacturing a coated iron golf club head, groove processing is performed on at least the club face of the club head base on which no scoring line is formed to form the scoring line, and then the coating forming treatment ( Paragraph 0007 of Japanese Invention Patent Laid-Open Publication No. Hei 10-277185). Also, Japanese Patent Laid-Open Publication No. 2008-23178 describes a golf club head in which milling (cutting with a milling machine) is performed on the club face to...

AI Technical Summary

Problems solved by technology

[0004] As described in the aforementioned Japanese Patent Laid-Open Publication No. 10-277185, after groove processing is performed on the club face of the club head base to form score lines, if a plating layer is formed by performing a plating layer forming process, the score lines will be damaged. Decreased precision at the edge where the side surface of the wire groove meets the club face

That is, when grooved the face of the base body of the club head to form the score line, although the shape of the edge where the side surface of the score line groove and the face intersect is ideal, if a plating layer is formed for the purpose of improving the service life, etc. , because the coating has a certain thickness, it will reduce the accuracy of the above edge
