abrasive products. SUBSTANCE: abrasive article with predetermined minimum penetrability degrees for liquids and gases includes 40-80% of volume with intercommunicating porosity, abrasive grains and binder in quantities necessary for different types of highly effective grinding processes. High penetrability for liquids and gases and intercommunicating porosity provide open structure of ducts allowing to liquids and gases to pass through volume of abrasive article and to remove slime off ground part at grinding process. EFFECT: enhanced efficiency of grinding. 40 cl, 10 tbl, 10 ex
