Stone milling also produces a nutty flavor and texture that consumers were finding less than ideal for some of their recipes. Millstones also wear down after use, and have to be "dressed" or sharpened about every 90 days or so, creating concern that corundum dust from the grinding stones became part of the flour being produced. These ...

Grinding Wheel: Specifications & Manufacturing Process by ...
In grinding process, the process of breaking of abrasive grains & exposing sharp edges is called as friability. When the grains break down under pressure, the new edges for cutting emerge or are exposed. During this process, the binding material also gets removed and the grains which have become blunt get free and are removed.
Principles of Modern Grinding Technology | ScienceDirect
Grinding is a term used in modern manufacturing practices to describe machining with high-speed abrasive wheels, pads, and belts. Grinding wheels come in a wide variety of shapes, sizes, and types of abrasives. In recent decades, grinding has been evolved both for producing very high quality parts and for fast economic production.

Grinding Wheel - an overview | ScienceDirect Topics
W. Brian Rowe, in Principles of Modern Grinding Technology, 2009. Grains as Cutting Tools. A grinding wheel removes material in a similar way to a micro-milling cutter. In micro-milling, the cutting tools are identical in shape. The situation is quite different in grinding. The cutting tools in a grinding wheel are the grains, and material removal depends on their shape and position.
Eight tips for effective grinding - The Fabricator
Effective grinding requires operators to apply enough pressure at the correct angle to let the grains—the "cutting tool" of a grinding disc—remove the most metal in the shortest time, while not prematurely wearing the disc or burning out the grinding tool. The variables abound, and managing them effectively can be vital for efficient part flow.
