FIELD: measuring equipment.
SUBSTANCE: invention relates to measurement equipment, particularly to methods of determining parameters of impact on barrier of grains of diamond-abrasive powders with irregular geometrical shape. Method comprises accelerating grains of diamond-abrasive powders in a compressed air jet, and then striking them on stiff barrier. Stiff barrier is made of material whose hardness enables to obtain prints thereon, dimensions of which enable to determine their volumes. Grains of diamond-abrasive powders are accelerated to speeds generating forces insufficient for their destruction.
EFFECT: possibility creating a controlled process of classifying grains by strength, and therefore predicting service life of diamond-abrasive tools.
