Diamond powders
There is wide range of grit size ranging from micropowder to very rough powders. The choice of the grit size cannot be categorized. When making the choice it is important to consider the future purpose. It is possible to define three basic operations: lapping or frosting, fine grinding, rough grinding.
For operations of lapping or frosting micropowders are used. Usually they are mixed in diamond pastes with different diamond concentration. Diamond powder size and concentration depend on surface roughness one wishes to have.
Diamond powders of sizes 10/20 - 106/125 micron are usually used in diamond tools for fine grinding operation, 125/150 - 425/500 - for rough grinding.
