ABSTRACT:
A method for finishing surfaces of workpieces includes a honing process with at least two method steps. In one of the method steps the surface, for example, the inner wall of a bore, is honed to a predetermined final dimension whereby a very fine structure with minimal depth of honing traces is generated so that a great portion of the surface functions as the supporting surface. In a further method step, which can be performed before or after the finishing-honing step, crossed grooves are provided in the surface by subjecting the surface to a stream of a medium, especially a laser, whereby the pattern of the grooves provides a lubricant reservoir for the future use of the workpiece. The treatment with a stream of a medium does not cause deformations at the edges of the grooves. This ensures an optimal distribution of the lubricant.
