Quick Summary

A grinding wheel is a tool with a rotating abrasive wheel used to change the shape or dimensions of hard materials, typically metal. These wheels are made from manufactured abrasives like silicon carbide or aluminum oxide, mixed with a bonding agent and fused by baking. The wheel is self-sharpening as dull grains break off, exposing fresh ones. Grinding wheels are essential in industry for creating precise components and smooth surfaces, used in everything from automotive manufacturing to sharpening tools. They can remove large amounts of metal or grind miniature precision parts to accuracies measured in micrometers.12
