Schleifkörnungen

Schleifkörnungen, often translated as abrasive grains, are the fundamental components of abrasive tools used for material removal and surface finishing. These grains are typically made from hard, sharp materials that can effectively cut or grind softer materials. The choice of abrasive grain is critical and depends on the material being worked and the desired outcome. Common abrasive grain materials include aluminum oxide, silicon carbide, diamond, and cubic boron nitride. Each possesses unique properties: aluminum oxide is a versatile and cost-effective choice for many metals and woods, silicon carbide is harder and more brittle, suitable for harder materials like stone and glass, while diamond and cubic boron nitride are extremely hard, used for superhard materials like ceramics and carbides.

The size of the abrasive grains, known as grit size, is another crucial factor. This is measured using a numerical system where lower numbers indicate coarser grains and higher numbers indicate finer grains. Coarse grits are used for rapid material removal and shaping, while fine grits are employed for achieving smooth surface finishes. The shape and structure of the grains also influence their performance. Sharp, angular grains tend to cut more aggressively, whereas rounded or blocky grains may offer a smoother, less aggressive action. Manufacturers carefully control the production of these grains to ensure consistency in size, shape, and hardness, which directly impacts the abrasive tool's efficiency and lifespan.
