Saint-Gobain New Product Grinding Technology Exchange Conference

Saint-Gobain Abrasives was founded in 1665. The Saint-Gobain Group, headquartered in France, manufactures, processes and sells high-tech materials and services. As a branch of the highly functional materials of the Saint-Gobain Group, Saint-Gobain Abrasives designs, manufactures and sells all of the three leading brands of NORTON, WINTER and FLEXOVIT, and is the world's largest manufacturer of abrasives and the only one. A global company that produces all five categories of abrasive products. Products include bonded abrasives, coated abrasives, industrial superabrasives, resin cutting and polishing, and diamond products for the construction industry.

Saint-Gobain's latest grinding technology application technology exchange meeting in the automotive and auto parts industry

Saint-Gobain Ceramic CBN Wheel

With the rapid development of the automotive industry, automotive and its component manufacturers are constantly pursuing production scale and product standardization in production. This trend has driven diamond and cubic boron nitride CBN superhard materials in automobiles and their zeros. Applications in the component manufacturing industry. Diamond and cubic boron nitride CBN superhard abrasives have high hardness, good wear resistance, thermal stability and thermal conductivity compared to ordinary alumina abrasives and silicon carbide abrasives, making them ideal for grinding and cutting. Grinding and trimming some workpieces that are difficult to machine with conventional abrasives.

Taking automobile camshaft grinding as an example, the production efficiency of grinding with ceramic bond CBN grinding wheel is obviously improved. When selecting the ceramic bond CBN grinding wheel, the working speed of the grinding wheel is at least 60m/s to ensure the grinding amount of the grinding process, the service life of the grinding wheel and the surface quality of the workpiece after machining.

In addition, with the continuous development of modern electronic products, the precision manufacturing of electronic molds has higher requirements for tool grinding products, especially in slot grinding applications, not only to grind very thin grooves, but also to make The bottom is machined at right angles, resulting in a dedicated grinding wheel that meets the needs of high precision clear angles. Norton Hummingbird Hummingbird is the latest high-performance ceramic tool grinding wheel from Saint-Gobain Abrasives. It uses high-quality corundum abrasives and Saint-Gobain's newly developed innovative ceramic bond formulation Vitrium 3, regardless of shape retention, tissue uniformity or Excellent performance in grinding stability.

In 2013, the ceramic bond Vitrium 3 will be used globally. Norton's revolutionary bonding technology has once again stood at the forefront of today's "super-precision, high-efficiency" grinding technology. Compared to conventional binders, Vitrium3 offers significant advantages in terms of grinding efficiency, surface roughness, wheel life and machining accuracy. Vitrium 3 bonding technology can be widely used in the manufacture of various high-speed grinding wheels, especially for new ceramic abrasives such as Quantum and TG. The strong combination of the two makes the product have high metal removal rate and shape retention, which is very suitable for aviation. A variety of high-speed, high-efficiency grinding processing fields such as aerospace, automotive parts, gears and bearings. Advantages include: higher grinding speed (80m / s); better shape retention, reducing wheel dressing frequency; more open structure, can be applied to large tissue number formula, reducing workpiece burns.
