The process of elastic grinding block achieving fine grinding on hard stone materials involves multiple key steps and technical points.1. Basic composition and characteristics of elastic grinding blockElastic grinding block is essentially made of high molecular polymer (such as rubber, resin, etc.) mixed with abrasive particles. The abrasive particles are evenly distributed and conical, and are semi-fixed abrasives. Its characteristic is that the bonding strength of the binder to the abrasive particles is relatively small, which can provide sufficient elasticity and adaptability during the grinding process, so as to better fit the stone surface and achieve fine grinding.2. Steps and technical points of fine grindingChoose a suitable grinding block: Choose a suitable elastic grinding block according to the hardness and grinding requirements of the stone. The hardness, particle size and shape of the grinding block will affect the grinding effect. Ensure that the grinding block has sufficient elasticity and wear resistance, and can maintain stable performance during long-term grinding.Pretreatment of stone: Before grinding, the stone needs to be pretreated, such as cleaning and decontamination, to ensure that it will not be affected by impurities during the grinding process. For stones with cracks or defects, they need to be repaired or filled first to avoid expanding the defects during the grinding process.Rough grinding and finishing: Use coarser abrasives for preliminary grinding to remove large scratches and uneven parts on the stone surface. During the rough grinding process, apply force evenly to avoid new scratches or damage to the stone. After rough grinding, use finer abrasives for finishing to make the stone surface smoother.Fine grinding: The elastic grinding block plays a key role in the fine grinding stage. Due to its elasticity and adaptability, it can better fit the tiny bumps on the stone surface and achieve fine grinding. Use suitable grinding tools and grinding pastes, and cooperate with elastic grinding blocks for grinding. Maintain uniform speed and pressure during grinding to avoid over-grinding or under-grinding. During the grinding process, check the grinding effect at any time and adjust the grinding strategy and the choice of abrasive in time.Polishing and glazing: After fine grinding, use polishing tools and polishing paste to polish the surface of the stone. Polishing can improve the gloss and smoothness of the stone surface. After polishing, use appropriate protective agents or polishing agents to protect the stone to enhance its durability and beauty.3. Precautions and operating tipsSafety protection: During the grinding process, wear protective equipment such as goggles, gloves and dust masks to protect the eyes, skin and respiratory tract from dust and splashes. Ensure the safety of the operating environment, stay away from flammable and combustible materials, and keep the work area clean.Grinding strategy: According to the hardness and grinding requirements of the stone, formulate a reasonable grinding strategy. For stones with higher hardness, harder grinding blocks and finer abrasives can be used for grinding. During the grinding process, gradually replace finer abrasives and softer grinding blocks to achieve better grinding results.Maintenance and care: Regularly clean and maintain the grinding tools and elastic grinding block to keep them in good working condition. Avoid direct sunlight and humid environment when storing to extend the service life.In summary, the process of fine grinding of elastic grinding block on hard stone materials involves multiple steps and technical points such as selecting suitable grinding blocks, pre-treating stones, rough grinding and trimming, fine grinding, polishing and glazing. Through reasonable grinding strategies and operating skills, fine grinding and polishing of stone surfaces can be achieved to improve the beauty and durability of stones.
