METHOD AND TOOL FOR PRODUCING A SURFACE OF PREDETERMINED ROUGHNESS

Described is a method for producing an e.g. cylindrical surface that has a surface structure of predetermined geometry suitable for application of material by thermal spraying. In this connection, a geometrically predetermined groove structure of minimal depth and width is introduced into an e.g. cy...

Zusammenfassung:	Described is a method for producing an e.g. cylindrical surface that has a surface structure of predetermined geometry suitable for application of material by thermal spraying. In this connection, a geometrically predetermined groove structure of minimal depth and width is introduced into an e.g. cylindrical surface of a substrate to be coated, that is preferably machined to size, by means of a tool that is preferably embodied as a follow-on tool in that a groove cross-section is processed successively to a final size. In order for the surface to be producible in mass production with constant quality, the method is designed such that the groove structure is worked in such that first a base groove is introduced with a groove bottom width that is smaller than the groove bottom width of the finished groove. Subsequently, the groove, for example at least one flank of the base groove, is processed for producing an undercut groove profile by a non-cutting action or cutting action wherein preferably the introduced groove structure is deformed in such a way that the groove openings are constricted by upsetting deformations of material.
