In the known structuring of sliding bearing surfaces (1) by means of microscopically small depressions (27) to be introduced, more particularly produced by means of electrochemical removal of material, it is proposed according to the invention to limit the proportion by area of the depressions within the structured area to from 15% to 40% of the total structured area since this reduces the outlay for processing but a larger proportion by area of the depressions (27) barely brings about an increasing reduction of the friction in the sliding bearing.

In a method for producing toothed sections on workpieces, a toothed section is firstly produced by means of a first tool in the region of a first end face of a workpiece to be toothed. The produced toothed section is reworked on the peripheral face by means of at least one second tool in the region of the first end face, while the toothed section is further produced. If the toothed section is also produced in the region of the second end face by means of the first tool, the reworking in the region of the first end face is already completed, so the toothed section can also be reworked in the region of the second end face. Short cycle times are thereby achieved with a low machine-related outlay.
