    IntroductionWhat Is Grinding?Grinding ProcessThere are several processes of manufacturing that are important for the conversion of raw materials into finished goods. Most of these processes deal with giving a new shape and form to the raw materials either by changing their state or shape. One such important process is grinding, and it is very useful technique for metal removal at fast rates and for the high level finishing of final products.
