Background
At present, in the traditional metallographic sample preparation and transmission electron microscope film sample preparation process, the manual mechanical grinding mode is simple, and the grinding effect is seriously dependent on the technology of operators. While transmission electron microscopy requires a sufficiently thin thickness of the sample to be observed, typically 5 to 50nm. The conventional method is to cut the test specimen into thin sheets having a thickness of about 500 μm using a wire cutting method, and then gradually thin the sheets to 40 to 80 μm using sandpaper having different roughness. The influence of the applied pressure on the tissue and sample preparation quality needs to be considered in the grinding process, so that the thickness reduction of sand paper with different roughness needs to be controlled; meanwhile, the thickness is as thin as possible on the premise of uniform thickness, so that a large number of scientific researchers need to resort to or develop various mechanical thinning operation rules and auxiliary equipment thereof. For example, the grinding of reciprocating or "8" shaped tracks by pressing a sheet against metallographic coated abrasive with rubber or rubber is the simplest manual grinding method. However, the friction force between the rubber eraser and the sample is limited and the rubber eraser often slips, so that the grinding efficiency is low; in addition, the method has the advantages that the subjective artificial control factor of the grinding position is large, the rigidity of the rubber eraser is low objectively, and the thickness uniformity of the thin sheet is low.
The structures described in the patent nos. CN201559120U and CN202517353U can effectively solve the above-mentioned problems, but there are other prominent problems in the mechanical polishing process, namely, how to solve the control of the polishing thinning amount.
