Comparison of Burnishing Process with Other Methods of Hole Surface Finishing Processes Applied on Brass Materials

Abstract

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.

Modeling of Deep Rolling as a Distortion Compensation Strategy during Profile Grinding

“…Identification of mechanical parameters. The interaction of the deep rolling velocity, the normal force, and the tool diameter results in a continuous contact pressure on the workpiece [9]. The velocity 𝑣𝑣 𝑑𝑑𝑑𝑑 corresponds to the relative movement between the tool and the component.…”

Flat diamond sliding burnishing surface roughness investigation

“…Ball, roller, and sliding burnishing types are popular in some cases referred as processes in other cases referred as methods based on the shape of the burnishing element or the type of contact between the workpiece and burnishing element. What makes this process different from the other surface finishing post-process is its good surface finishing ability and inducing positive compressive stress that boosts its surface integrity (Rodríguez et al, 2012;Ovali & Akkurt, 2011).…”

Influence of Some Microchanges Generated by Different Processing Methods on Selected Tribological Characteristics

“…Ovali and Akkurt developed experimental research to compare the results of using burnishing and other hole surface finishing processes in the case of specimens made of brass materials [9]. They noticed that the highest hardness and the best surface quality were obtained when applying the burnishing process.…”
