Embodiment 1
[0034] (1) Sample preparation:
[0035] A 316 stainless steel sample with a surface condition of No.1, with a thickness of 6 mm, processed into a cuboid structure with a length of 6 cm and a width of 5 cm, and cut 9 pieces in total;
[0036] (2) Fixed sample:
[0037] Adhere 9 samples to the fixture of Φ300mm and 25mm thick aluminum disc with hot melt adhesive. The lower surface of the fixture is a horizontal plane, and the upper surface is a surface with certain protrusions around the periphery, which is used to fix the pressure. Module, stick 3 specimens on each fixture (such as figure 2 ), and then put the sample together with the fixture on the Φ640mm polishing platform. There are three fixed gears on each polishing process platform, and each gear uses two pulleys to fix the fixture, which can fix 3 fixtures at the same time (such as image 3 ), the pressure is applied by the weight module above the fixture (such as Figure 4 );

Embodiment 2
[0051] (1) Sample preparation, 304 stainless steel sample with surface state No.2B, thickness 0.5mm, processed into a cuboid structure with length 4cm, width 3cm, and cut 9 pieces in total;
[0052] (2) Fix the sample, stick 9 samples to the fixture of Φ300mm and 25mm thick aluminum disc through hot melt adhesive, the lower surface of the fixture is a horizontal plane, and the upper surface is a certain protrusion on the periphery. Surface, used to fix the ballast module, 3 samples can be stuck on each fixture (such as figure 2 ), and then put the sample together with the fixture on the Φ640mm polishing platform. There are three fixed gears on each polishing process platform, and each gear uses two pulleys to fix the fixture, which can fix 3 fixtures at the same time (such as image 3 ), the pressure is applied by the weight module above the fixture (such as Figure 4 );
[0053] (3) Coarse throwing:
[0054] After the sample is fixed, the sample is roughly polished. The o...
