The article deals with the influence of the surface roughness, processed by different technological methods to ware resistant characteristics’ of the surface layer of ship machines and details high-precision parts. As the technological methods of processing parts was used rotary cutting, grinding with vibration damping, rotating honing, lapping with metered readout surface layer material and the flexible rolling. It is established that the use of a rotary cutting method as a finishing treatment forms not only additional deformed high ware resistant surface layer of parts, at the same time is provided high productivity. The process of grinding with vibration damping significantly reduces the transfer of the abrasive particles on the treated surface, improves accuracy, quality and surface layer ware resistant characteristics. During the rotary honing discontinuity of single grain cutting is combined with continuity of chip formation process, practically no metal buildup to the working surface of the cutting part of the tool occurs, the temperature in the cutting area is reduced, which brings to get details with surface layer of high-quality ware resistant. During the lapping of the surface layer material the optimum value of the highly deformable surface layer thickness is provided. Because of the possible regulation abrasive action to the treated surface, reliable ware resistant layer could be obtained. Flexible rolling enables the implementation of non-rigid thin-walled parts processing with stable, secure, adjustable forces without degrading their accuracy, quality and ware resistant characteristics.
