Grinding of metals is a complex material removal operation involving cutting, ploughing, and rubbing depending on the extent of interaction between the abrasive grains and the workmaterial under the conditions of grinding. it is also a stochastic process in that a large number of abrasive grains of unknown geometry, whose geometry varies with time, participate in the process and remove material from the grinding mill.

Two broad categories of grinding action are recognized; one where negligible ploughing and rubbing take place and where the plunge velocity versus normal force intensity curve is a straight line through the origin, the other where ploughing and rubbing predominate and the plunge velocity versus normal force intensity curve is concave upward.

In recent years, increasing interest in the mechanics of grinding as a metal cutting process has resulted in a considerable step forward in understanding the fundamental parameters, though no complgrinding mill.From observations of individual grinding scratches and an analysis of the experimental results, it is concluded that virtually all of the grinding energy is expended by viscous deformation. material removal occurs by flow into chips with silicon carbide abrasive and by brittle fracture preceded by viscous deformation with diamond abrasive.

Basic grinding theory provides an overview of the general process of grinding . grinding occurs at the point of contact between an abrasive wheel and a workpiece. like any other cutting process, grinding removes material in the form of chips. in order for a wheel to grind properly, its abrasive grains must wear and self-sharpen at a consistent rate.In a grinding machine, there is an electric motor which supplies the motion power to the grinding wheel with the help of a belt and pulley. so when we start the electric motor the motor rotates at a certain rpm 150-15000 rpm, it may change according to the types of grinding machine with the help of v-belt and cone pulley the grinding wheel also starts rotating and we perform the operation.Oct 23, 2020 grinding is an abrasive machining process that uses a grinding wheel as a cutting tool. learn about grinding of metals and mechanics of grinding process. flash sale: 25 off certificates and diplomas!
