At the moment when the manufacturing industry is moving towards high-quality development, precision machining and surface treatment technology have become the key links to determine product quality and added value. As a professional manufacturer who has been deeply involved in the field of abrasives for many years, Jin Rui Abrasive and Abrasive Factory has always followed the development trend of the industry and gained a deep insight into the actual processing pain points of end users. Recently, it officially launched the upgraded oilstone and polishing disc series products. By virtue of its stable cutting performance, uniform grinding performance and fine surface treatment effect, this series of products quickly gained extensive attention from the industries such as mold manufacturing, auto parts processing, precision hardware and medical devices once they were put on the market. At present, many leading enterprises have signed bulk purchase orders, and the market feedback is positive.  First, the core advantages of the product: giving consideration to the double breakthrough of efficiency and accuracyIn the field of metal processing and surface treatment, how to obtain ideal surface finish while ensuring cutting efficiency is always the core challenge faced by technicians. The high-performance oilstone series launched by Jin Rui Abrasive and Abrasive Factory this time is aimed at the depth optimization of this pain point. This series of products are made of high-quality microcrystalline corundum, silicon carbide and other advanced abrasives, combined with a special proportion of binder system, and through strict temperature control sintering process, which ensures the uniformity of internal structure and the stability of microstructure of the products. In practical application scenarios, the oilstone series shows excellent comprehensive performance. For hard and brittle materials such as hardened steel, die steel, high-speed steel, etc., oilstone can quickly remove the knife marks and lines left by the previous process and effectively level the surface; For aluminum alloy, copper alloy and other non-ferrous metal materials, it can effectively avoid the surface scratch and blockage problems easily caused by traditional abrasives and maintain a stable cutting force. At the same time, the optimized binder formula endows the oilstone with good self-sharpening, and new sharp abrasive particles can be constantly exposed during use, thus prolonging the service life of the product and reducing the waste of working hours caused by frequent tool replacement.Second, in-depth application scenarios: helping customers solve practical process problems"The final finish of the mold surface is directly related to the demoulding effect and appearance quality of plastic parts." A senior technical engineer from Zhejiang Mould City said after using Jinrui's new products, "We have tried many brands of oilstones before, either the cutting force is not enough, or it is easy to drop particles and cause scratches. Jin Rui's new product is well balanced, which can not only quickly remove the white layer left by electric discharge machining, but also directly transition to the polishing process with fine particle size, and the overall efficiency is improved by nearly 20%. " This kind of feedback is not a case. In the field of automobile parts manufacturing, the person in charge of an enterprise producing engine valve parts mentioned that there has always been an efficiency bottleneck in the chamfering and polishing process of the valve stem end. "The original polishing disc wears quickly and changes frequently, and it needs to be rebalanced every time it is changed. Jin Rui's polishing disc can be used when it is attached, and the dynamic balance is well done. The service life is about one-third longer than the original, and the comprehensive cost is reduced after conversion. " The person in charge of the production of Jin Rui Abrasive and Abrasive Factory said: "We have always stressed that product research and development cannot be separated from application scenarios. The reason why this upgrade focuses on the uniformity of abrasive particles and the toughness of binder is precisely because when we visited customers, we found that what we are most concerned about is not how prominent a single parameter is, but whether the product can run stably for the whole life cycle while ensuring the cutting force. Our goal is to help customers produce more qualified workpieces in a unit time and truly reduce the comprehensive use cost. " Third, focus on manufacturing details: quality assurance and customized services in parallel.As a professional manufacturer with many years of manufacturing experience in the field of abrasives, Jin Rui Abrasives Factory always puts process stability and product consistency in the first place. The enterprise is equipped with advanced batching and mixing system, automatic molding press, precise temperature-controlled sintering kiln and complete set of testing equipment. From raw material storage to finished product delivery, each batch of products has undergone strict particle size analysis, hardness test and grinding ratio verification, ensuring that every oilstone and every polished disc delivered to customers meet the established quality standards. In addition to standardized product lines, Jin Rui also has strong non-standard customization capabilities. In view of the special needs of some customers, enterprises can undertake customized processing business of non-standard sizes, special-shaped specifications and specific particle size combinations according to incoming drawings and samples. Whether it's a long-hole grinding whetstone or a special-shaped polishing block with a specific curvature, Jin Rui's technical team can make targeted adjustments from the formula to the molding process, and provide customized solutions that fit the actual working conditions.Fourth, deepen the market layout: win-win cooperation and share opportunitiesAt present, with the continuous development of China manufacturing towards intelligence, green and high-end, the demand for high-performance abrasive tools in the field of precision machining is showing a rapid growth trend.

The traditional grinding wheel often faces many challenges, such as low grinding efficiency, short service life, easy to burn the surface of the workpiece, when facing new workpieces such as high-strength alloys and composite materials. Similarly, in the field of precision knives and professional kitchenware, users have higher expectations for the grinding fineness, self-sharpening and durability of sharp whetstone.   1. Ceramic bonding technology of "in-nucleus growth": this is the soul of "Laoyuan" series of grinding stone and grinding wheel. By precisely controlling the growth direction and density of microcrystals in the binder, we make the overall structure of abrasive tools more uniform and tough. Compared with the traditional technology, the new binder improves the strength of bonding bridge by more than 40% while maintaining excellent self-sharpening, which means that grinding wheel can maintain extremely high shape stability in high-speed and heavy-load grinding, effectively avoiding deformation problems such as "bell mouth", greatly prolonging the service life of products and reducing the cost of single use. 2. Nano-scale pore control system: heat dissipation and chip removal during grinding are the key factors affecting machining quality. Engineers in Jin Rui built an efficient and uniform three-dimensional chip removal channel inside the grinding tool by introducing nano-scale hole-making technology. This innovation makes "Ruifeng" series products have excellent heat dissipation performance in dry grinding, which can effectively prevent thermal damage of workpieces. In wet grinding, the cooling liquid can penetrate into the grinding point more quickly, and the chip removal is smooth, thus realizing a colder, faster and cleaner grinding experience. This technology is undoubtedly a great boon for users who pursue the ultimate smooth surface. 3. Gradient composite structure design: especially applied to our high-end sharp whetstone products. We innovatively adopt a three-stage abrasive gradient composite structure of "coarse-medium-fine", and a single grinding stone can complete the whole process from rapid sharpening to fine polishing. The coarse particles in the surface layer are responsible for efficient material removal, the middle particles in the middle layer are initially leveled, and the fine particles in the bottom layer realize the final mirror-level polishing. This "trinity" design not only simplifies the operation process, saves the time for users to switch between grinding stone with different granularity, but also ensures the straightness and consistency of cutting edge grinding, which is favored by professional chefs and carpenters.in-depth analysis of series products: tailor-made for different scenariosHigh-performance grinding wheel: specially designed for heavy-load grinding in large steel mills, foundries and shipbuilding enterprises.

Precautions before use1. Lubrication selection -Special oil for oilstone: low-viscosity mineral oil or special grinding oil, which can reduce blockage and improve cutting efficiency. -Water-based lubrication: suitable for fine polishing, but it is necessary to avoid long-term immersion to prevent the substrate from softening. -Dry grinding is prohibited: grinding without lubrication will lead to rapid wear of oilstone and damage the surface of workpiece. 2. Surface pretreatment -Before the new oilstone is used for the first time, it is recommended to lightly grind the surface with #600 grit sandpaper to remove the hard particles that may be produced during transportation.Matters needing attention in use1. Pressure control -Rough grinding (#120-#400): Moderate pressure (about 3-5 kg/cm) can be applied. -Fine polishing (above #800): It needs to be lightly pressed (1-2 kg/cm) to prevent the particles from falling off and affecting the finish. 2. Temperature management -When grinding continuously for more than 15 minutes, the cooling should be suspended (the temperature of the oilstone should be ≤60℃), and high temperature will reduce the strength of the binder. 3. Direction of motion -Cross grinding method (alternating grinding in 45 direction) is adopted to avoid groove wear caused by one-way movement.Safety warningProtective equipment: dust mask and goggles must be worn, and silicon carbide dust may irritate respiratory tract. Forbidden scene: it can't be used to polish soft metals such as lead and tin (it is easy to cause metal adhesion on the surface of oilstone). Scrapping standard: When there is obvious depression or uneven particle size on the surface of oilstone, it should be replaced in time.       ▶Contact us/Witness the power of Made in China‍Tel: 13954968158Email: 13954968158@163.comOfficial website: jrabrasive.com
