grinding wheel, when grinding gears [4]. The diamond grains on the dressing wheel causes undulations on the grinding wheel surface and when grinding the gear, also the gear flank surface will have undulations (waviness). These undulations typically have wavelengths of about 0.5 mm and amplitudes of approximately 4μm.

CONSTRUCTION OF GRAIN GRINDING MACHINE ABSTRACT The aim of the project is to construct a domestic grain grinding machine to be powered by electric motor through pulley and belt transmission. The project is to perform mostly blending and grinding on grains e.g beans, maize, melon, millet and such other food crops.

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.
