Which of the following indicates the amount of superabrasive grit in a grinding wheel?

Explanation

Explanation:- Concentration indicates the amount of Superabrasive grit in a grinding wheel. Superabrasives Superabrasives make up a special category of bonded abrasives designed for grinding the hardest, most challenging work materials. These materials offer extreme hardness, but they are more expensive than conventional abrasives (silicon carbide and aluminum oxide). The concentration of a Superabrasive layer depth by the abrasive concentration and the addition of the super abrasive wheel is the amount of abrasive in the abrasive layer. Because of the high cost of super abrasives, a thin layer of a grinding wheel may be attached to a core material so that only that layer of a grinding wheel may be attached to a core material so that only the outer layer is useable of super abrasives Important Points High concentrations (100-200 ) are suitable for mass production of parts and tools made from tungsten carbide, HSS, ceramic products, creep-feed, and profile grinding. Medium concentrations (75-125) used for tool maintenance, resharpening, and internal grinding. Low concentrations (25-100) are suitable for cutting discs, honing, dressing, drilling, and general uses.
