Background
In order to ensure the stability of the Wear system at high rotational speeds, a high-precision friction and Wear tester developed in countries such as the United states of America, Europe, Japan and the like usually defaults to a disc-type Test specimen having a diameter of 2.74 inches (about 69.6 mm) and a height of 0.26 inches (about 6.6 mm) and defines it as a Standard disc-type Test specimen size, according to ASTM G99-2017 "Standard Test Method for Wear Testing with a needle dial gauge", which is established by the American society for Testing and materials.
In the friction wear test, the state and the degree of wear are directly related to the surface quality of a detected sample, and the surface quality of the detected sample must be effectively controlled before the test. The mechanical polishing is to remove a very thin layer of metal on the ground surface of a sample by means of grinding and rolling actions of very fine polishing powder to form flat and small-defect surface quality. The surface quality is precisely controlled by improving the surface smoothness of the sample and eliminating fine scratches, so that the accuracy and the effectiveness of the friction and wear test result are improved. Therefore, on the premise of not considering non-environment-friendly polishing modes such as electrolytic polishing and the like, a mechanical polishing mode with certain processing efficiency is needed to be adopted to treat the surface quality of the sample.

In order to reduce the poor effect of surface quality control of the disc-shaped sample caused by human factors in the grinding and polishing process and improve the polishing quality and efficiency, a full-automatic grinding and polishing machine is required.
Although the full-automatic grinding and polishing machine can realize multi-station grinding and polishing, the size of the circular sample clamping groove is small (the full-automatic grinding and polishing machine is only suitable for the circular sample with the diameter of about 30mm at most), and the surface polishing of the large-size disc-shaped sample for the friction and wear test cannot be met, so that an auxiliary clamp matched with the full-automatic grinding and polishing machine is urgently needed to be designed when the full-automatic grinding and polishing machine is used for processing the surface polishing quality of the large-size disc.
