  The article deals with the changes in the surface layer of the ring of rolled bearing steels. The additional method of hydrostatic roller burnishing operation is applied on samples of material 100Cr6 (EN 10132-4) and changes in the surface layer of the workpiece are then evaluated. The simulation using finite element method was used to better understand the ongoing phenomena.

  The paper deals with the issues of machining by finishing turning of hardened materials in the production of bearing rings. In this area, grinding is mainly used as standard technology. It is a demanding production process requiring precision machinery and optimally set technology. Under these conditions, the mass-production can offer components with prescribed degrees of accuracy in the tolerance level from IT 4 to IT 5 and with the arithmetical mean deviation of the profile in the range between Ra = 0.4 and Ra = 0.8. For these conditions, there has been a long search for alternative technology that would ensure the same required values with simpler demands on manufacturing process. One of the developmental paths was focused on turning with the use of advanced cutting materials for machine tools. It is primarily the use of cubic boron nitride (CBN). A cheaper and more affordable option is also the application of cemented carbide of group H. This carbide is intended primarily for finishing machining of the materials difficult to machine. Regarding the tool geometry, either the classic variant with radius edge or the Wiper variant can be used. On the world market, reputable companies offer these materials in the form of replaceable inserts; nevertheless their application for machining of e.g. hardened materials also depends on other decisive factors. Basically, this is a system of machine-tool-workpiece where its stability is of particular importance; in other words the rigidity of clamping. As shown in performed and evaluated practical experiments, it is not easy to determine the initial conditions. The experience gained from this area is the subject of this article.

  The paper describes the determination of various factors lubricants that affect the durability of rolling bearings or general rolling contact. Their knowledge is a prerequisite for use in calculating the life of roller bearings from two perspectives. Above all, it will be possible to determine more accurately the durability of rolling bearings or rolling contact with all the economic consequences. The deepening of this information will enable purposeful and controlled increase of rolling bearing durability.

  Cutting process of shaped profiles is associated with different shapes of curves what means changes of directions which cutting tool moves in. Most of the cutting processes are taking place in milling operations. Such operations are composed from mutual motions of both cutting tool and workpiece. The relative motion then involves complex vector analysis of rotational motion of the cutting tool and a curve motion of the workpiece.
