In this article, effects of traditional surface machining processes and a newly used surface finishing process called burnishing process on a brass material are compared on the basis of microstructure, circularity, cylindricity, and surface roughness. For this reason, test samples made of brass material which is a non-ferrous metal were prepared to be widely used in many fields of machining industry as it accurately reveals deformation effects of surface finishing processes, and those samples were subjected to drilling, lathing, reaming, grinding, honing, and burnishing. After these processes, hole surface roughness, cylindricity, and change in microstructure were analyzed. All surface machining processes were performed under constant depth of cut, cutting speed, and feed rate. Data collected after experimental research indicates that the best combination of surface characteristics is obtained by burnishing process, in comparison to all other different methods of finishing. Also the highest hardness and best surface quality of machined surface are provided with burnishing. All results show that burnishing should be preferred to provide the optimum characteristics in hole surfaces subjected to continuous deformation and corrosion.
