The Three Pillars of Ceramic Abrasive Grain Performance | …
2020/3/6· Not until the invention of silicon carbide (1891) and brown fused aluminum oxide (1905) did grinding wheels and also sandpaper (coated abrasives) have engineered grains to drive performance. The earliest abrasive grains and their successive generations of product all utilized the electro-fusion process, operating at temperatures up to ~2000C.
Hard Choices: Diamond or CBN? | Gear Solutions …
This means that more than 90 percent of the grinding heat is removed from the grinding zone with the CBN plated wheel grinding process. Strength and resistance to the thermal and chemical attack while maintaining sharp cutting edges during use makes CBN the superior choice compared to conventional abrasives such as silicon-carbide and aluminum-oxide.

Silicon Carbide - an overview | ScienceDirect Topics
Here it may be noted that silicon-carbide is harder yet more brittle than abrasive such as aluminum oxide. Since its grain fractures readily and maintain a sharp cutting action, silicon-carbide abrasives are generally used for grinding hard, low tensile strength materials such as chilled iron, marble and granite, and materials that need sharp cutting action such as fibers, rubber leather or
Lapidary Fundamentals: Cabochon Cutting
They come in silicon carbide or diamond and in grits from 100 to 50,000. In the long run, these belts cost more than wheels with eedded diamond, but the difference isn’t as significant as with the silicon carbide grinding wheels.
