Description
Technical Field

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 seriously depends on the technology of an operator. Transmission electron microscopy requires a sufficiently thin thickness, typically 5 to 50nm, of the sample to be observed. The conventional method is to cut the sample into thin sheets with a thickness of about 500 microns by wire cutting, and then gradually thin the sheets to 40 to 80 microns using sandpaper of different roughness. The influence of applied pressure on the tissue and sample preparation quality needs to be considered in the grinding process, so that the thinning thickness of the sand paper with different roughness needs to be controlled; meanwhile, the thickness is required to be as thin as possible on the premise of uniform thickness, so that the scientific researchers need to help or develop various mechanical thinning operation rules and auxiliary equipment thereof. For example, grinding with a reciprocating or "8" shaped track by pressing a sheet against a metallographic sandpaper with rubber or rubber is the simplest manual grinding method. However, the rubber eraser often slips due to limited friction with the sample, so the grinding efficiency is low; in addition, the method has large subjective artificial control factors of the grinding position, objectively, the rigidity of the rubber eraser is low, and the thickness uniformity of the sheet is not high.
The structures described in patents CN201559120U and CN202517353U can effectively solve the above problems, but there are other outstanding problems in the mechanical grinding process, namely how to solve the control of the grinding thinning amount.
