Study of the Electrostatic Method of Applying Abrasive Grains to the Grinding Tool Backing

The article is devoted to the study of the problem of the electrostatic method of applying abrasive to the surface of the backing when manufacturing flexible grinding tools. An original technique for the manufacture of experimental samples with abrasive grains oriented at various angles is presented in the article. The diagrams of apparatuses for the orientation of grains relative to the backing surface are given. The optimal angle of grain orientation was revealed and substantiated experimentally. The parameter of the influence of changing the distance between the electrodes on the degree of concentration of grains on the backing surface of the samples is analyzed. The percentage ratios of oriented abrasive grains relative to their total number for various grain sizes are presented. The relationship between the angle of inclination and the actual number of grains per unit surface of the backing is determined. Based on the statistical data obtained, conclusions are formulated that can be used in the manufacture of flexible grinding tools.
