mill (grinding) - wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ()

hardness testing insight

Cutting and grinding may introduce deformations. These must be removed by polishing down to 6.0, 3.0, or 1.0 m, depending on the hardness test load. For small loads (less than 300 gf1) the surface needs to be completely free of deformations, and the specimens require oxide or electrolytic polishing to obtain a completely damage-free surface

Grinding and Polishing Guide. Grinding should commence with the finest grit size that will establish an initially flat surface and remove the effects of sectioning within a few minutes. An abrasive grit size of 180-240 [P180-P280] is coarse enough to use on specimen surfaces sectioned by an abrasive wheel. Hack-sawed, bandsawed, or other rough
