[0002] In the production of metallurgical materials, the physical properties of metallurgical materials are crucial performance parameters. However, in the process of physical property testing, the materials need to be processed into various standard samples to facilitate the corresponding instruments and equipment to test the physical properties. In order to fully test the physical properties and accuracy of the materials, multi-sample testing is generally adopted, which requires several or even dozens of samples, and has high requirements on the surface of the samples. Therefore, the samples need to be polished.

[0003] The grinding of the sample is usually carried out by a belt sander, which is a kind of grinder that uses a sanding belt to grind the sample. The sample can only be ground one piece at a time on the belt sander, that is, after grinding one piece, the next piece can be ground. The continuity is poor, the grinding efficiency is low, and the grinding accuracy is poor. Utility Model Content
