POLISHING DEVICE, PROCESSING METHOD OF POLISHING MEMBER, MODIFICATION METHOD OF POLISHING MEMBER, SHAPE PROCESSING CUTTING TOOL, AND SURFACE MODIFICATION TOOL

摘要

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.
