Description
Technical Field

Background
The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art.
Metallographic sample preparation is an important means in the scientific research process, and aims to display the real tissue of a sample. The inventors have found that, although the sampling process has been simplified compared to before with the advance of the art, there are some problems. For example, when a sample is ground by using a grinding and polishing machine, only single-side grinding can be performed; when a sample is electrolyzed, only single-side electrolysis can be carried out, and when multi-side grinding and electrolysis are required, repeated clamping is required; and finally, when the manufactured sample is subjected to sem detection, only single-side detection can be carried out by one-time clamping. Meanwhile, the SEM sample has high requirement on the cleanliness of the detection surface, so that the sequential grinding, electrolysis and detection of a plurality of side surfaces are difficult to perform through manual adjustment; even if sequential manual adjustment completes the sampling and detection of multiple sides of a single sample, the manual error causes the data registration difficulty between the multiple sides to be still large compared with the micro-structure of micron and submicron level. These problems not only lower the sample preparation efficiency, but also have a certain effect on the accuracy of the research result, for example, when three-dimensional EBSD information of the material is required, the XY-plane EBSD data, YZ-plane EBSD data, and XZ-plane EBSD data obtained by sample preparation of three samples respectively have a larger error than the XY-plane EBSD data, YZ-plane EBSD data, and XZ-plane EBSD data obtained by using the same sample are more difficult to register. Therefore, to summarize, the prior art has the following problems:
1. and the sample preparation and collection of a plurality of samples or the sample preparation and collection of a single sample are time-consuming, labor-consuming and high in cost.
2. For the condition that a single sample is manually adjusted and is subjected to sample preparation and collection for multiple times, due to multiple clamping, coordinate registration of data on different collected side faces is difficult to perform, and the error is large; and the surface of the finished sample can be damaged during subsequent sample preparation on the side surface, so that the sample cannot be effectively stored.
