Golf club head and surface finishing tool and method for forming pattern thereon

Abstract

A surface finishing tool and a fabricating method for forming a pattern on a golf club head are provided. The surface finishing tool comprises a shank, a resilient cylinder, and a rubbing head. The shank has a center axis, and the resilient cylinder is disposed along the center axis and fixed on an end of the shank. The rubbing head has a rough surface and is disposed on the resilient cylinder. The fabricating method applies the surface finishing tool to form the pattern on the golf club head, wherein the surface finishing tool is driven to rotate along the center axis first. Then, the surface finishing tool is moved for keeping the rough surface of the rubbing head contacting with the golf club head, wherein the resilient cylinder is deformed along a profile of the golf club head as the rubbing head contacts with the golf club head.

1 . A surface finishing tool for forming a pattern on a golf club head, the surface finishing tool comprising: 
 a shank, having a center axis;    a resilient cylinder, disposed along the center axis and fixed on an end of the shank; and    a rubbing head, having a rough surface and is disposed on the resilient cylinder.    
   
   
       2 . The surface finishing tool according to  claim 1 , wherein the resilient cylinder is made of rubber.  
   
   
       3 . The surface finishing tool according to  claim 1 , wherein the rubbing head comprises abrasive cloth.  
   
   
       4 . A fabricating method for forming a pattern on a golf club head by using the surface finishing tool recited in  claim 1 , the fabricating method comprising: 
 driving the surface finishing tool to rotate along the center axis; and    moving the surface finishing tool for keeping the rough surface of the rubbing head contacting with the golf club head to form the pattern on the golf club head, wherein the resilient cylinder is deformed along a profile of the golf club head as the rubbing head contacts with the golf club head.    
   
   
       5 . The fabricating method according to  claim 4 , wherein the surface finishing tool is driven by a rotary machine.  
   
   
       6 . The fabricating method according to  claim 5 , wherein the rotary machine comprises a driller, a lathe, or a miller.  
   
   
       7 . A golf club head having the pattern made by the fabricating method recited in  claim 4 .  
   
   
       8 . The golf club head according to  claim 7 , wherein the pattern is a whirlpool pattern.
