A grinding machine which is popularly known as a grinder is a power tool or machine tool used for grinding. Just as other machine tools, it is a type of machining process that uses an abrasive wheel as the cutting tool. The abrasive grain on the wheel's surface cuts a small chip from the workpiece through a shear deformation.Small wheels of 25mm diameter cost up to 10$ for conventional abrasive and for diamond up to 200$.; Large wheel of 500mm diameter and 250mm width, the cost is about 8000$ to 20000$.; Life of Grinding Wheel. When a grinding wheel is applied to the workpiece, the sharp edges of the abrasive grains which are cutting, will, in the end, lose their cutting effect and become dull.
