Abstract

The invention provides a tool for clamping a metallographic specimen and a method for grinding and polishing the specimen. The tool comprises a grip, a handle and a chuck which are connected in sequence, the tool further comprises a magnet which is arranged between the handle and the chuck. The magnet is fixed between the handle and the chuck by the periphery of the chuck, and the tool adsorbs a metallographic specimen by the magnet part exposed out of the hollow structure of the chuck; after the tool is stably clamped, the metallographic specimen is clamped by the convex edge and the notch, the metallographic specimen is adsorbed and fixed by the magnet, the grip and the handle are held by hands, and the metallographic specimen is ground and polished on the grinding disc, and the metallographic specimen is relatively stably fixed, so that the grinding and polishing forming rate of the specimen is increased; and the grinding and polishing efficiency is guaranteed through the simple and convenient using method.

Description

technical field [0001] The invention belongs to the technical field of metallographic sample grinding and polishing, and in particular relates to a tool for clamping metallographic samples and a method for grinding and polishing the sample. Background technique [0002] Metallographic inspection (metallographic inspection) is mainly to determine the three-dimensional spatial morphology of the alloy structure by using the principle of quantitative metallography, using the measurement and calculation of the metallographic microstructure of the two-dimensional metallographic sample grinding surface or thin film, so as to establish the alloy composition, Quantitative relationship between organization and performance. This technology not only greatly improves the accuracy of metallographic inspection, but also improves its speed and greatly shortens the working time. In a sense, metallographic inspection is the research and analysis of the internal structure of metals on the bas...
