Today grinding spans from very crude and rough applications in cutting of materials at high material-removal rates (MRR) to finishing and ultraprecision processes. The latter can achieve surface roughness values in the range of Ra = 0.3 nm and accuracy, planarity and size of geometrical features in the range of 10 nm.
