Material Grinding Bonding. Able for grinding sharp edges, removing a thin layer or for work on hard, brittle material and small objects.Coarse grains are more effective for large-scale material removal, for grind-ing tough material and large objects.Softer bonding is usually suitable for fine grains and harder bonding for coarse grains, where feed force is often high.

bonding material or ' bond'. The abrasive grains provide the wheel with its cutting points, which in turn help in cutting the material to the required dimensional accuracy or help impart a fine surface finish. The arrangement of the abrasive grain and the bond in the grinding wheel gives a definite characteristic known as 'structure' or 'pores'.
