Grinding of Metals: Origin and Cutting Action | Industries,

Grinding can also be considered as a machining process, i.e. process of removing metal, but comparatively in smaller volume. To grind means ‘to abrade’, to wear away by ‘friction’ or ‘to sharpen’. In grinding, the material is removed by means of a rotating abrasive wheel. The action of grinding wheel is very similar to that of a milling cutter.Bolivia - Mining | SelectUSA.gov,Mining in Bolivia has been a dominant feature of the Bolivian economy as well as Bolivian politics since 1557.
