First, particle grinding: when the abrasive particles change from coarse grinding to fine grinding to polishing. The traces of abrasive grinding on the surface of the stone show a smooth, smooth and delicate surface. When the depth reaches 110 microns, the surface processed by the stone polishing machine will appear mirror-like luster, radiant and bright.
Second, the particle grinding of the stone polishing machine consists of the following processes:
1. Rough grinding: requires a deep knife, high grinding efficiency, coarse grinding lines, and a rough surface. Mainly remove the saw blade marks left by the product in the previous process and grind the product's flatness and modeling surface in place.
2. Semi-fine grinding: remove the rough grinding traces to form new finer lines, and the product surface is smooth and smooth.
3. Polishing: The surface is as bright as a mirror, with a certain degree of mirror gloss (above 85 degrees).
Third, the principle of physical chemistry:
There are two polishing processes for stone polishing machines, which are divided into dry polishing and wet polishing. The polishing stone is between "dry and wet" when the stone product has a physical and chemical effect. Dry polishing is when the temperature of the stone surface rises to evaporate water, resulting in an increase in the concentration of the polishing stone, thereby achieving a strengthening effect. When the gloss of the product begins to meet the ideal requirements, the gloss reaches 85 degrees or higher.
