Grinding Operation an overview ScienceDirect Topics
During mill operation, grinding balls wear and are reduced in size In doing so, the grinding characteristics change The extent of wear would depend on the characteristics of the rock present, such as surface hardness, density and composition The abrasive action on the surface of the balls increases with time This grinding operation is carried out only on cylindrical jobs It is of two types; external and internal cylindrical grinding, an external grinder is used to remove excess material from the outer surface of the workpiece Whilst the internal is done for smoothening the internal surface of a hole or any cylindrical workpieceOperations that can be performed on grinding machine Assume that a surfacegrinding operation is being carried out under the following conditions: D = 200 mm, d = 01 mm, v = 40 m/min, and V = 2000 m/min These conditions are then changed to the following: D V = 150 mm, d = 01 mm, v = 30 m/min, and V = 2500 m/minAssume that a surfacegrinding operation is being carried
