Abrasive machining is not considered to be a precision grinding process, but that's not to say it isn't precise. Abrasive machining can take the place of "large-chip" machining processes like milling, planing, broaching, and turning. Compare the surface finish and the precision achieved with the large-chip processes to the surface ...
