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

摘要

It is an objective of the present invention to provide a polishing device that allows shape processing and shape modification to be easily performed on a polishing surface having a non-planar shape. The polishing device includes a polishing member (10), a tool (41), and a contact mechanism (40). The polishing member (10) includes a polishing surface that is shaped in conformance with the shape of an end (KE) of a workpiece (K). The tool (41) functions as a shape-processing cutting tool or a surface modifying tool that has the same shape as the shape of the end (KE). The shape-processing cutting tool processes the polishing surface of the polishing member (10) to be shaped in conformance with the shape of the end (KE). 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 (40) brings the tool (41) into contact with the polishing surface of the polishing member (10).
