fine grinding of metals in metallurgy

Grinding of Metals: Origin and Cutting Action Industries

3. Cutting Action in Grinding: It will be observed from Fig. 20.1 that a grinding wheel consists of abrasive particles, bonding material and voids. The projecting abrasive particles act like cutting tool tips and remove metal. A properly selected grinding wheel exhibits self-sharpening action.

Metallographic Polishing and Grinding Kemet

Fine grinding is usually done on abrasive belts with grit sizes between 320 and 600. Following each grinding stage, the specimen should be cleaned with soap and running water to prevent carrying coarse abrasive particles to the next specimen. One large abrasive grain can ruin the surface of a finely ground and polished specimen.
