The milder abrasives like 32 and 38 Aluminum Oxide are best for lighter precision grinding operations on steels and semisteels, while the intermediate 57 and 19 Aluminum Oxide abrasives are used for precision and semiprecision grinding of both mild and hard steels. The severity of the grinding operation also influences the choice of grade.
stone durability. For some stone types, durability can be assessed to a certain degree using procedures for evaluating concrete durability outlined in ASTM C666, Standard Test Method for Resistance of Concrete to Rapid Freezing and Thawing. However, the temperature range in this test (0 to 40 degrees Fahrenheit) does not
A dull, earthy appearance indicates a stone likely to decay. 177. Absorption. One of the most important tests for the durability of stone is that of the porosity, or degree with which the stone absorbs moisture, since, other things being equal, the less moisture a stone absorbs the more durable it will be.

The results of this test series differ quite a bit from the first test series, even though I am using the same plane blades and the same SiC bench stone.
1.1. Durability estimation. Stone durability depends heavily on both strength and pore structure properties, although it has mainly been estimated either from strength or from pore structure properties. The durability estimators are defined by the petrophysical parameters of the stone, which are usually obtained for its characterisation.
