Problems solved by technology

Among these steps, the most time-consuming and laborious is the grinding and polishing in the sample preparation process, and these steps can only be processed manually. At this time, the grinding and polishing machine has become the gospel of the majority of material researchers.

[0005] However, the most common laboratory grinding and polishing equipment on the market requires manual operation, that is, manual clamping, and constant observation of the flatness of the sample and adjustment of the pressing force of the hand on the resin-embedded metal sample, which is time-consuming and labor-intensive. There is no guarantee that the processed samples can well meet the observation needs, and the gains outweigh the losses. It needs repeated repetitions, which is a great pain for researchers. Therefore, it is very necessary to design a set of auxiliary clamping devices for metallographic grinding and polishing machines. , which can liberate the hands of researchers, save the time of grinding and polishing samples, and at the same time ensure higher grinding and polishing precision. This device is of great significance to material researchers
