Machining 101: What is Grinding? | Modern Machine Shop
Associate Editor, Modern Machine Shop. On its surface, grinding seems simple: a machine takes a rotating tool (usually a wheel) with abrasive grains and applies it to a workpiece's surface to remove material. Each grain is its own miniature cutting tool, and as grains dull, they tear from the tool and make new, sharp grains prominent.
