A technologically advanced method of modifying synthetic diamond grinding powders is described. The method involves applying to the surface of the grains of powder liquid-phase coating of a saturated solution of heat-resistant compounds. An experimental batch of AC6 125/100 grinding powders modified in this way was made. Boron and aluminum oxides and sodium and calcium chlorides were used as the cover material. The study of morphometric characteristics, technological properties and uniformity of the obtained grinding powders is carried out. The test results of experimental grinding wheels in the cutting layer of which the experimental grinding powders modified according to the developed technological scheme were used are presented. The correlation analysis of interrelation of operational characteristics of experimental grinding wheels and morphometric characteristics, technological properties and uniformity in the shape of the projection of the grains of modified grinding powders is carried out. An analytical presentation of the results of the study of this relationship in the form of empirical mathematical dependences was performed. Recommendations on the areas and methods of the most effective application of the tested experimental grinding wheels and directions of possible continuation of the researches carried out in the work are given.
