SAMPLE HOLDER, POLISHING JIG AND POLISHING DEVICE USING THESE AS WELL AS POLISHING METHOD AND MOUNTING METHOD OF ROD-SHAPED ABRASIVE SAMPLE

PROBLEM TO BE SOLVED: To provide a polishing device that is suitable for polishing an end surface of a rod-shaped abrasive sample made of fiber-reinforced polymer composite materials, without using adhesives and an embedding process.SOLUTION: A polishing jig 40 includes: a polishing jig body for holding a sample holder 20 while setting up; at least peripheral three guide protrusions provided in a facing surface of an abrasive seat 52 of a polishing device 50; at least one mounting hole having an inner diameter larger than an outer diameter of the sample holder 20; a sample holder attaching part for mounting the sample holder 20 in the mounting hole; and a polishing device attaching part to be mounted to a rotating shaft 54 of the polishing device 50. The height of the guide protrusion is configured to make a suitable state where the tip part of a rod-shaped abrasive sample attached to the sample holder 20 comes into abutment with the abrasive seat 52 and polishes the tip part of the rod-shaped abrasive sample 10, while attaching the sample holder 20 in the mounting hole.SELECTED DRAWING: Figure 6 【課題】接着剤や埋め込みプロセスを用いることなく、繊維強化型ポリマー複合材料製の棒状研磨用試料の端面研磨に適した研磨装置を提供する。【解決手段】試料ホルダー２０を立設した状態で保持する研磨治具と、研磨装置５０の研磨用シート５２の対向面に設けられた少なくとも周辺三カ所のガイド突起部と、試料ホルダー２０の外径よりも大きな内径を有する少なくとも一つの装着穴と、該試料ホルダー２０を該装着穴に装着するための試料ホルダー取付部と、研磨装置５０の回転軸５４に取り付けられるための研磨装置取付部とを備え、ガイド突起部の高さは装着穴に試料ホルダー２０を取り付けた状態で、試料ホルダー２０に取り付けられた棒状研磨用試料の先端部が研磨用シート５２と当接して、棒状研磨用試料１０の先端部を研磨するのに適した状態とできるように構成した研磨治具４０を有する。【選択図】図６
