ABSTRACT:
Method for manufacturing improved contact surfaces, particularly contact surfaces in rolling bearing components such as rings or rolling bodies, is disclosed. The method subjects a surface of the rolling bearing component to a hard turning machining operation for forming by means of a hard turning tool a rolling or sliding contact surface. The hard turned surface is subjected to a finishing operation to remove the basic turning groove structure in a light machining way such that micro-pockets created in the hard turning operation remain. The hard turning tool during the hard turning machining operation is subjected to a vibration, substantially in the longitudinal direction of the tool, thereby creating in a controlled manner in the hard-turned surface a number of indentations, which are substantially arc-shaped in cross-sectional direction, prior to the finishing operation. Indentations improve lift-off and lubricating properties during later operation of the rolling bearing.
