Abstract
A roughening tool for roughening the cylindrical surface of a bore in a particular metallic workpiece, e.g. the piston running surface of a cylinder bore or cylinder liner in an internal combustion engine, by generating a defined microstructure of a plurality of circumferentially spaced apart circumferential microgrooves. The roughening tool has a tool main body which can be driven in rotation about an axis of rotation and a multiplicity of circumferentially cutting cutting tools arranged at a defined axial distance from one another on the tool main body. According to the invention, the cutting tools are each formed from a disc milling cutter and each disc milling cutter has at least one cutting element with a multiplicity of cutting teeth arranged at an axial distance from one another. In addition, a method for roughening a cylindrical surface.
