Design of the finishing machine for rolling bearing's elements
 Cagaš, Radek ; Křenek, Miloš (referee) ; Košťál, David (advisor)
The thesis deals with the design of the device that is used to improve the quality of the surface of spherical rollers. Spherical rollers are used for the measuring of the conditions in the EHD contact. The high roughness and waviness of the spherical rollers’ surface is a problem. Several machining methods are described in the theoretical part. The overview in theoretical part has been used for choice of the machining methods (lapping and abrasive polishing). The spherical rollers‘ machining system, its construction, electronics and control systems are described in the next section. The last part is focused on testing of assembled device, and on checking its functionality. The desired roughness of the spherical rollers' surface, suitable for successful interferometric measurement, was achieved by combining the selected machining methods. The roughness and waviness achieved was Ra0.01 micron Wa0.022 microns.
