Diamond grinding discs offer a long-wear surface that provides excellent surface flatness for a wide variety of materials. Fixed diamond particles in Buehler's diamond grinding discs provide consistent removal rates and extended lifetime with only an occasional dressing to maintain the surface.
Mohs hardness is a resistance to being scratched, while Vickers hardness is a resistance to indentation under pressure. The graph shows the great difference between the Vickers hardness of corundum and diamond - which are only one unit apart on the Mohs hardness scale.
Hardness – structure Hardness identification The hardness of a CBN or diamond grinding wheel is identified by a letter after the grit size. Superabrasives however, do not cover the total range found in conventional wheels i.e. very soft Ato very hard Z. Individual solutions for maximum economy The structure of a grinding wheel is
Dec 15, 2016· The higher cross-feed rates, which may be, exceptionally, even in the order of 1/2 to 1/3 wheel width, are used for roughing, particularly of work materials having low hardness. For finishing, as well as for grinding high strength or sensitive materials, a slow cross feed, in the range of 1/8 to 1/12 of the wheel width, is applied.

Grinding wheel hardness. Hardness is rated from A-Z with 'A' being the weakest bond and 'Z' being the strongest. A weak bond is preferred for grinding harder materials while a stronger bond is desired for softer materials. A typical weak bond for steel would be in the 'F, G or H' range.
A diamond tool is a cutting tool with diamond grains fixed on the functional parts of the tool via a bonding material or another method. As diamond is a superhard material, diamond tools have many advantages as compared with tools made with common abrasives such as corundum and silicon carbide

Diamond's great hardness relative to other materials has been known since antiquity, and is the source of its name. Diamond hardness depends on its purity, crystalline perfection and orientation: hardness is higher for flawless, pure crystals oriented to the <111> direction (along the longest diagonal of the cubic diamond lattice).
Manufactured diamonds are used for grinding aluminum oxide cutting tools, very hard steels and cemented carbide. Cubic boron nitride is sharp, cool and extremely hard abrasive (2.5 times harder than aluminum oxide and almost as hard as diamond). It is used for grinding super-hard, high-speed steels, hardened cast irons, stainless and die steels.
