Grinding is used to finish workpieces that must show high surface quality (e.g., low surface roughness) and high accuracy of shape and dimension. As the accuracy in dimensions in grinding is of the order of 0.000025 mm, in most applications it tends to be a finishing operation and removes comparatively little metal, about 0.25 to 0.50 mm depth.
autogenous grinding machines fracture of the media particles also occurs by both impact (self breakage) and attrition. The relative motion of the media is determined by the tumbling action which in turn is quite strongly influenced by the liners and lifters that are always fixed inside the shell of the mill.
