The article provides the justification of the parameters of the polishing regimes when machining surfaces of parts made of copper and aluminum in order to smooth their surface layer. It has been established that the technological support of the surface of laser mirrors with high reflectivity ρλ at a wavelength of 10.6 microns, the surface of parts with low absorptivity As in the wavelength range from 0.2 to 2.5 microns is associated, first of all, Values of the contact potential difference (CPD). The ratio of the height parameters of the surface roughness Ra / Rmax can be used to control the surface defects after applying the finishing methods of processing. Smoothing of the surface layer should be carried out step by step, reducing the grain size of the abrasive. After grinding, it is necessary to perform abrasive polishing with diamond paste ACM 5/3 for 1 minute. After thorough cleaning of the surface from the residuals of the working medium, the treatment with diamond paste ACM 2/1 should be applied for 1 minute and at the final stage the treatment should be carried out with a suspension of nanopowder Al2O3.
