Peas polisher Wholesale Price tells you that the key to the operation of the polishing machine is to try to get the maximum polishing rate, so as to remove the damaged layer produced during polishing as soon as possible. Peas polisher Wholesale Price tells you that at the same time, the polishing damage layer will not affect the final observed tissue, that is, it will not cause false tissue.

Peas polisher Wholesale Price tells you that the former requires the use of coarser abrasives to ensure a greater polishing rate to remove the polished damage layer, but the polishing damage layer is also deeper; the latter requires the use of the finest The material makes the polishing damage layer shallower, but the polishing rate is low.
Peas polisher Wholesale Price tells you that the best way to solve this contradiction is to divide the polishing into two stages. The purpose of rough polishing is to remove the polishing damage layer. This stage should have the largest polishing rate. The surface damage caused by rough polishing is a secondary consideration, but it should be as small as possible; followed by fine polishing (or final polishing), Its purpose is to remove the surface damage caused by coarse polishing and minimize the polishing damage.
When the polishing machine is polishing, the grinding surface of the sample and the polishing disc should be absolutely parallel and evenly pressed lightly on the polishing disc, and attention should be paid to prevent the sample from flying out and new grinding marks due to too much pressure. At the same time, the sample should be rotated and moved back and forth along the radius of the turntable to avoid local wear of the polishing fabric too quickly. During the polishing process, the micro powder suspension should be continuously added to keep the polishing fabric at a certain humidity.
If the humidity is too high, the grinding effect of polishing will be weakened, and the hard phase in the sample will appear embossed, and the non-metallic inclusions in steel and the graphite phase in cast iron will produce a "tailing" phenomenon; if the humidity is too low, the heat generated by friction will make the sample When the temperature rises, the lubricating effect will decrease, the grinding surface will lose its luster, and even black spots will appear, and the light alloy will scratch the surface.
Peas polisher Wholesale Price tells you that in order to achieve the purpose of coarse polishing, the rotary speed of the turntable is required to be low, preferably not more than 600r/min; the polishing time should be longer than the time required to remove the scratches, because the scratches need to be removed Deformation layer. After rough polishing, the polished surface is smooth but dull, and there are uniform and fine wear marks under the microscope, which need to be eliminated by fine polishing.
Through the above introduction and analysis of the Peas polisher Wholesale Price, hope it helps you.
