ABSTRACT:
When honing working cylinders for reciprocating piston-type machines or engines, e.g. internal combustion engines, unlike in conventional honing methods working takes place with a much higher axial speed than circumferential speed. This gives a mark pattern, which admittedly differs significantly from the axial direction, but runs more in the axial direction than in the circumferential direction. On the dominant mark pattern can be superimposed in a finishing operation a honing mark pattern, which has much finer honing marks and creates a plateau surface with diamond-shaped islands pointing in the working direction of the piston. A thus treated working cylinder, in the case of limited wear, leads to much lower oil consumption on the part of the engines.
