Burnishing of thesample was carried out after previous turning. The process of turning was carried out by a carbide cutting tool with amark T15K6 plate with the test sample fixed in a holder with the snap-action tailstock center. Burnishing was performedusing two different methods of fixing the sample (in the centers and in a three- jaw chuck with a snap-actiontailstock center). The roughness parameters were measured using the automated profilograph-profilometer of the BV-7669 model. The studies have shown the possibility of macrorelief formation on the burnished surface if the sample wasmachined in the centers and its absence if the sample was machined in the holder with a snap-action tailstock center. Inorder to obtain the empirical relationships linking the surface roughness with the diamond burnishing process parameters(pressing force, speed, feed, the initial peak-to-trough height and the radius of the diamond burnishing tool) a seriesof single-factor experiments treated with the use of the method of least squares was carried out. The results obtainedcorrelate well with the experimental results previously obtained in studying the process of diamond burnishing with theuse of a diamond burnishing tool made of synthetic diamond ASB-1.</p>Diamond burnishingburnishing process parametersnatural diamondmacroreliefsurface roughnessАлмазное выглаживаниепараметры процесса выглаживаниянатуральный алмазмакрорельефшероховатость поверхности[1.
