Description
Technical Field
The utility model relates to a metallographic specimen clamping tool field specifically is a thin slice metallographic specimen grinds and throws anchor clamps.
Background
The observation of the metallographic microstructure of a metal sample is an important part in material research, and due to the influence of practical factors, the surface roughness and the smoothness of the metal sample often cannot meet the requirements of tests, so that the surface of the metal sample needs to be polished and polished to prepare the metal sample with the surface roughness and the smoothness meeting the test requirements. The direct grinding and polishing of the sample surface by the hand-held sample method has the following disadvantages: 1) due to uneven force application, a plurality of planes are easy to appear on the surface of the metal sample, and subsequent processes such as polishing, corrosion and the like are influenced; 2) for a sheet metal sample, the metal sample is directly polished by adopting a hand-held sample method, so that the sheet metal sample is easy to fly off a grinding disc; 3) the efficiency of directly polishing the sheet-like metal sample by the hand-held sample method is low, and a great deal of time and energy of test personnel are wasted.
