Polishing device, processing method of polishing member, modification method of polishing member, shape processing cutting tool, and surface modification tool

Abstract

A polishing device includes a polishing member, a tool, and a contact mechanism. The polishing member includes a polishing surface that is shaped in conformance with the shape of an end of a workpiece. The tool functions as a shape-processing cutting tool or a surface modifying tool that has the same shape as the shape of the end. The shape-processing cutting tool processes the polishing surface of the polishing member to be shaped in conformance with the shape of the end. The surface modifying tool modifies the polishing surface to be shaped in conformance with the shape of the portion to be polished. The contact mechanism brings the tool into contact with the polishing surface of the polishing member.

         10 . A polishing device comprising:
 a polishing member including a polishing surface that is shaped in conformance with the shape of a portion to be polished of a workpiece;   a shape-processing cutting tool or a surface modifying tool having the same shape as the portion to be polished, wherein the shape-processing tool processes the polishing surface to be shaped in conformance with a shape of the portion to be polished, and the surface modifying tool modifies the polishing surface to be shaped in conformance with the shape of the portion to be polished; and   a contact mechanism that brings the shape-processing cutting tool or the surface modifying tool into contact with the polishing surface.   
     
     
         11 . The polishing device according to  claim 10 , wherein the contact mechanism brings the shape-processing cutting tool or the surface modifying tool into contact with the polishing surface in predetermined cycles. 
     
     
         12 . The polishing device according to  claim 10 , wherein through a process of bringing a surface of the polishing member that differs in shape from the portion to be polished into contact with the shape-processing cutting tool or the surface modifying tool, the polishing surface of the polishing member is formed to be shaped in conformance with the shape of the portion to be polished. 
     
     
         13 . The polishing device according to  claim 10 , further comprising:
 a motor that rotates the polishing member from below.   
     
     
         14 . The polishing device according to  claim 10 , further comprising:
 a base including an upper surface, wherein when the polishing member is located on the upper surface, the base is rotated integrally with the polishing member.   
     
     
         15 . A shape-processing cutting tool that is a member used in the polishing device according to  claim 10 , wherein
 the shape-processing cutting tool has the same shape as the portion to be polished, and   the shape-processing cutting tool processes the polishing surface to be shaped in conformance with the shape of the portion to be polished.   
     
     
         16 . A surface modifying tool that is a member used in the polishing device according to  claim 10 , wherein
 the surface modifying tool has the same shape as the portion to be polished, and   the surface modifying tool modifies the polishing surface to be shaped in conformance with the shape of the portion to be polished.   
     
     
         17 . A method for processing a polishing member, the method comprising:
 bringing a shape-processing cutting tool into contact with a polishing surface of the polishing member, wherein   the polishing surface is shaped in conformance with a shape of a portion to be polished of a workpiece, and   the shape-processing cutting tool has the same shape as the portion to be polished and processes the polishing surface to be shaped in conformance with the shape of the portion to be polished.   
     
     
         18 . A method for modifying a polishing member, the method comprising:
 bringing a surface modifying tool into contact with a polishing surface of the polishing member, wherein   the polishing surface is shaped in conformance with a shape of a portion to be polished of a workpiece, and   the surface modifying tool has the same shape as the portion to be polished and modifies the polishing surface to be shaped in conformance with the shape of the portion to be polished.
