3 thoughts on “What is the principle of grinding? And has its role?”

The basic principle of grinding is: This is a trace metal cutting movement. Its basic principle is the comprehensive effect of physical and chemistry. Physical action is the cutting effect of the abrasive on the workpiece. During grinding, the material that requires the research tool is softer than the material of the workpiece. When it is under pressure, the tiny particles (abrasives) in the abrasive agent are embedded on the surface of the research tool and become countless blades. Due to the relative movement of research tools and workpieces, the abrasives generate a small amount of cutting and squeezing the workpiece, and the surface of the workpiece is evenly cut off a thin metal to use the accurate surface of the research tools to gradually accurately get the workpiece to gradually be accurate Size accuracy and surface roughness. Is when using chromium oxide, ligaic acid, or other chemical abrasives to grind the workpiece, the metal surface in contact with air will form a kind of oxide film quickly, and the oxide film is easily ground The chemical effect of grinding. During the grinding process, the oxide film quickly formed (chemical), and was constantly grinded (physical effects). After repeated repeatedly, the surface of the workpiece met the predetermined requirements. The role of grinding: The size accuracy of the grinding parts can generally reach 0.005 to 0.001mm, so that the parts can reach accurate size. In grinding, the surface roughness of the workpiece processing can be minimized. General surface roughness is RA0.8 to 0.05 μm, and the minimum can reach RA0.006 μm. It with the help of research on the relative movement of the tools, the geometric shape of the workpiece can be more accurate. It because the surface roughness of the workers after grinding is small and accurate shape, the corrosion resistance and anti -fatigue strength of the workpiece also improved accordingly, thereby extending the service life of the part.
Functional soybeans do tofu —-, (1) Stone crystal treatment The stone crystal surface treatment is an emerging technology that reconnects in the stone surface layer and hardened. The principle is to make stone materials through physical and chemical methods The surface lattice softened, and a dense molecular arrangement layer was formed under the grinding of Baijie pad, and finally solidified the lattice. After the stone is treated hard, its hardness can increase the hardness of 2-3 Mohi, and the light is significantly improved.

(2) Daily care of stone
Tools, equipment and materials: ordinary single rubbing machine (better effort machine effect), water absorption machine, red hundred cleanliness Cushion, white polishing pads, watering pots, signs, waxing water, Italian marble crystal hard powder YM01, US NCL marble brightener 2501, dust push, glass scraper, waterwing device, dedicated wiper renovation disk (spare backup To. 2. According to different marble hardness and daily passenger flow frequency, the maintenance time can be up to 2 months to 1 year (for regular maintenance). 3. How to use: first thoroughly clean the surface of the marble, remove the original maintenance layer, adjust the marble crystal hard powder into a paste, apply it on the red pad, and use the wipe to grind the ground machine to grind the ground machine to grind the ground machine for grinding Add a small amount of water to always keep semi -dry and semi -wet moisturizing. Depending on different types of marble and wear degree repeatedly grinding through 3-5 minutes, high-gloss and high-gloss surface layers appear on the surface of the marble surface. Use the water absorbers to quickly absorb the residual ground objects, scrape them with water, and then use a white polishing pad for polishing. The surface of the marble is as bright as new. 4, daily maintenance: ① Push dust daily. ② spraying maintenance: 1-2 times a week will aggravate the machine and red pads (or 0#百) to carry out the spraying maintenance of the US NCL marble brilliant agent 2501. Spray an appropriate amount 201 on the ground, and each working area should be 1-2 square meters. The aggravator is evenly rolled with the brilliant agent, and it can be finely grinded to the light. Stochida: Steel cotton should be kept clean. If it is found, it should be replaced in time. When encountering light marble ground, it is necessary to use a red polishing pad to prevent the steel wire cotton black and pollute the light -colored marble. ③ Local key maintenance: Damage is naturally serious at the entrance, passage and pedestrian walking frequency. Use Yimi Crystal Hard powder to grind locally, and then use NCL marble brilliant 2501 to polish to restore the overall stone feeling of the lobby. The variety of natural stone materials, and each type of stone has its own different characteristics. Even if the same name is the same name, the difference is very different due to different origin. Therefore, during the maintenance process, fine -tuning should be performed based on specific stone and perennial work experience. The stone cutting, ground stone due to the processing process and processing accuracy of the mechanical equipment and processing accuracy during processing, resulting in uneven thickness of the board or being unreasonable during the placement and transportation on the way to put on hold and transportation. Unavoidable cutting ports. At the same time, in order to rush the construction period during construction, when the stone base is not dry or the construction is accidentally, it will cause cutting. In the past, the hand -tossing machine was generally used to repair the higher part, but the effect was very poor. It is manifested in: (1) The luster cannot be guaranteed, and the contrast with the original board is very large; (2) the local flatness and overall flatness cannot meet the standard requirements, which affects the decorative effect of the stone decoration.
