EN The paper presents the results of experimental studies involving the determination of the coefficient of friction (COF) of surfaces constituted by selected machining methods. The tests were carried out on a Bruker UMT2 stand using a ball made of 100Cr6 steel with a hardness of 62 HRC and a disc made of X210CR12 (NC11LV) steel with a hardness of 62 ±0.4 HRC in dry conditions. During the research, wear products were not removed from the sliding path. The paper presents methods of producing samples and corresponding surface characteristics. Significant differences in topography characterised the surfaces obtained due to various machining. The COF values at the beginning of the study and the COF values occurring after a specific route in the reciprocating cycle reached similar values, despite the significant differences in the surface topography of the tested samples. Significant COF changes as a path function were observed for samples produced with different machining methods.
