摘要： For producing a cylindrical surface that has a surface structure of predetermined geometry suitable for application of material by thermal spraying, a geometrically predetermined groove structure of minimal depth and width is introduced into the surface by a tool 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 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, 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 the introduced groove structure is deformed in such a way that the groove openings are constricted by upsetting deformations of material.

摘要： Described is a multi-blade cutting and drilling finishing tool for machining deep or stepped bores. The tool comprises at least a first blade set having a nominal diameter and blades distributed essentially uniformly over the circumference. In order to make it easier to guide the tool along the central axis, a guiding strip set in the form of very accurately positioned cutting inserts is located axially behind the first blade set with respect to the axial direction of the tool in which the tool advances forward to machine the deep or stepped bores. Each of the cutting inserts is aligned with one of the blades of the first blade set in a direction parallel to an axis of the tool, and each of the cutting inserts has a nominal diameter which is smaller than the nominal diameter of the first blade set by essentially twice the size of a lubrication gap forming between the guiding strip set and the deep or stepped bores when the tool is used.

摘要： Described is a multi-blade cutting and drilling finishing tool, in particular a reamer, for machining deep, especially stepped bores. Said tool comprises a set of blades having a predetermined nominal diameter and blades that are distributed in a substantially regular manner along the circumference. In order to make it easier to guide the tool along the central axis, a set of guiding strips in the form of very accurately placed and preferably cylindrically ground cutting inserts is located behind the set of blades in the advancing direction. Each of said cutting inserts is axially flush with the blades of the adjacent set of blades in the advancing direction of the tool and has a nominal diameter which is smaller than the nominal diameter of the set of blades substantially by twice the size of a lubrication gap forming when the tool is used.
