POLISHING ZIG FOR OBSERVING MICROSTRUCTURE FOR METAL

摘要

PURPOSE: A grinding jig for observing metallic structures is provided to prevent a body from becoming separated from a rotating shaft in a grinding process since an elastic member absorbs friction and shock to a metallic sample. CONSTITUTION: A grinding jig for observing metallic structures comprises a body(11), a screw groove(21), and grinding paper(31). The screw groove is recessed at one end of the body. The screw groove is screwed with a screw unit formed on the rotating shaft(1) of a grinder. The body is detachably mounted on the rotating shaft through the screw groove. The grinding paper is integrally installed on the other end of the body. The grinding paper rotates along the body mounted on the rotating shaft through the screw groove and grinds a metallic sample.
