Working principle of Grinding Machine: The working principle of a grinding machine is quite easier to understand.. 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 ...

Important steps in cylindrical grinding. 1. Check the work for size to make sure grinding stock has been allowed, and the same time note any tapering of the work. 2. Inspect the work centers to see that they are clean and true. Select machine centers of suitable diameters to fill the work's centers properly.

The main reason crankshaft grinding is done is because the crank wears over time. Over thousands miles the end play between the crankshaft and the bearings increases. When the "fit" between the bearings and the crank isn't perfect it lowers oil pressure and decreases lubricity. The less oil to the crank the faster it can wear out.

Surface Grinding Machine is a machine in which a grinding wheel is used as a cutting tool for removing the material from the surface of the workpiece. It is also called an abrasive machining process where abrasives are placed on the surface and corners of the grinding wheel so as to do the finishing process with much more accuracy.

Grinding Wheels. The size, material, and texture of the grinding wheel determine a bench grinder's function. A bench grinder usually has two different wheels- a coarse wheel, which is used for carrying out the heavy work, and a fine wheel, used for polishing or shining. The average diameter of a bench grinder is 6-8 inches.
