Opis:: The different technological operation can form the variety of surface with the different functionality. In this paper the surface texture produced by hard turning of a quenched 100Cr6 steel of 62-64 HRC hardness using mixed ceramic (MC) tools and subsequent superfinishing and multipass burnishing operations is characterized by means of a number of roughness parameters. Both conventional and wiper MC cutting tool inserts were employed. The main objective of this study is to improve service properties of the turned surfaces of bearing parts by additional removal and non-removal treatments in order to obtain smoother surfaces with lower surface roughness and better bearing characteristics.

Opis:: The purpose of this research is to test the applicability of ball burnishing for improving surface integrity produced in hard machining on parts made of high-strength, low alloy 41Cr4 steel with hardness of about 57 HRC. Machined surfaces were characterized using 2D and 3D scanning techniques. Moreover, the distribution of microhardness beneath the surface was determined and the microstucture of the sublayer was examined using SEM/EDS technique. This investigation confirms that ball burnishing allows producing surfaces with acceptable surface roughness and better service properties. The main conclusion is that this sequential technology can partly eliminate grinding operations when hard machining is not enough to produce the desired surface integrity.
