| 摘要 |
The invention relates to a method for roughening an inner surface (8) of a cylindrical bore (9), in particular a running surface in a cylindrical bore or cylinder liner of an internal combustion engine, wherein, by means of a rotating tool (1), which is moved in a translatory manner in the axial direction of the cylindrical bore (9) and has a radial cutting head (7), a chip (12) is lifted off by at least one cutting edge of the radial cutting head (7) and is broken away by means of a further edge or face of the radial cutting head (7), in order to produce the roughened surface. The invention is characterized in that the tool (1) is introduced into the cylindrical bore (9) or is passed through it, after which a positioning of the tool (1) in the radial direction takes place, and after which the removal of the material takes place by means of the rotating tool (1) when the tool is moved in its advancing direction (V) out of the cylindrical bore. A tool (1) is also claimed. |
