The basic properties of the abrasive

The grinding, lapping and polishing in the particulate material from the cutting action. Mainly for the manufacture of abrasive grinding tools, can be directly used in certain grinding and polishing work.

Abrasive should have the following cutting tools  properties: ① high hardness, should generally be higher than the material to be processed; ② appropriate strength, but also a sharp cutting edge in the grain can withstand cutting forces without fragmentation, when cut to a certain  synthetic diamond  obtuse extent exposed to partial fragmentation of new sharp edges; ③ high temperature stability, in the grinding temperature can maintain its inherent hardness and strength; ④ chemical inertness, and being easy to produce a chemical reaction processing of materials. These properties and the chemical composition of the abrasive, mineral composition, crystal morphology and integrity of the crystal and so on.
