The answer has to do with depths of cut. "When you turn or grind a part, the depths of cut could range from 50-100 microns or higher," Keshavan says. "Removing that amount of material in a short amount of time requires lot of energy, and the part heats up. Superfinishing removes 1-2 microns of stock on radius and requires less energy.".

Machining - Material removal processes
Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. The workpiece is typically cut from a larger piece of stock, which is available in a variety of standard shapes, such as flat sheets, solid bars, hollow tubes, and shaped beams.

Compared to manual grinding, automated tools can perform tasks like grinding, cutting, or milling, with a higher tool-on-contact time ratio and with optimized parameters sets. Since an automated process doesn't require a lunch break or a sick leave, they can also work for long hours and improve the production rate significantly.
Where Your Flour Comes From - Roller & Stone Milling ...
Up until the late 19th century, most millers used mill stones to mill the wheat into flour. Mill stones always come in a pair. Both are large round stones, with a flat top and bottom and are incredibly heavy. The bottom stone, the bed stone, stands still during the milling process. The top stone, or roller stone, rotates on top of the bed stone.
