Theories on Rock Cutting, Grinding and Polishing Mechanisms

Processes of cutting, grinding and polishing natural stones are made as a result of grinding-abrading mechanism developed on the use of different abrasive grains (mostly diamond and SiC). Wear intensity is named as cutting, abrading or polishing according to the speed, chip size and situation of obtained surfaces.
