The purpose of this work is to study  the patterns of scattering of sludge nanoparticles and polishing powder wear nanoparticles during polishing of copper and aluminum using dispersed systems of copper metaborate micro- and nanopowders with a dispersed medium in the form of kerosene or water, as well as the formation of a deposit of these nanoparticles on the working surface of the lapping tool, it was found that only sludge particles scattered forward and polishing powder wear particles scattered backward reach the lapping tool, the differential cross sections of which, varying within the limits of [2.3–102.0] Gb·sr-1 and [0.7–4.8] Mb·sr-1, significantly decrease with increasing separation between sludge nanoparticles, polishing powder wear nanoparticles and dispersed medium by dielectric permittivity. It is shown that the total scattering cross sections of nanoparticles sm and sp, varying within the limits of [0.05–1.78] Mb and [0.37–0.53] Mb, also decrease with increasing separation between sludge nanoparticles, polishing powder wear nanoparticles and dispersed medium in terms of dielectric permittivity, and the maximum sm/sp = 3.3 and the minimum sm/sp = 0.1, which are characteristic of the interaction of nanoparticles in the “copper–kerosene” and “aluminum–water” systems, indicate a more probable formation of a deposit on the working surface of the lapping tool from sludge nanoparticles – in the first case and from nanoparticles of polishing powder wear – in the second. It has been experimentally confirmed that during the polishing of copper using micro- and nanopowders of copper metaborate in a dispersed medium of kerosene, a deposit of copper particles was observed on the surface of the lapping tool, and during the polishing of aluminum in a water dispersed medium, a deposit of copper metaborate particles was observed.
