Then, the samples are ground using a grinding device. Finally, the thin sections are prepared. Subsequently, the preliminary processing of the thin sections is completed through the operations of sticking and sealing. Finally, the prepared rock and mineral thin sections are subjected to quality inspection using a microscope and other equipment to check whether the thickness of the thin sections is uniform, the surface of the thin sections is smooth and flat, and there are no defects such as scratches, bubbles, or mineral shedding, thereby completing the entire preparation process of the rock and mineral thin sections.

[0003] The existing automatic grinding device for rock and mineral thin section preparation has the following disadvantages: the existing device is not equipped with a pressure buffering structure.
