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.

09.14.2021. By Arvin Donley. It's been said the first flour miller was the first person who chewed on a wheat kernel. While the details of that milestone will never be known, we do know the transition to using millstones instead of molars to extract flour occurred around 6000 BC, and it remained the primary flour-making method for many centuries.
