Document Type and Number:
WIPO Patent Application WO/2020/038505
Kind Code:
A2
Abstract:
The invention relates to a circular milling tool (1) for producing a microgroove structure in the cylindrical surface of a bore, wherein the microgroove structure has a groove profile which is defined by a plurality of microgrooves which peripherally extend in a circular manner and are axially spaced apart from one another, having a tool base body (10) that can be driven about an axis of rotation and has a circumferential cutter set with a first circumferential cutting edge (38) and a second circumferential cutting edge (39), which are arranged in a row in the circumferential direction, wherein the first circumferential cutting edge (38) and the second circumferential cutting edge (39) each have a cutting profile which is different from the defined groove profile of the microgroove structure to be produced, and wherein the cutting profiles of the circumferential cutting edges (38, 39) of the circumferential cutter set, which are projected in the circumferential direction, overlap one another in the axial direction to such an extent that they jointly image the defined groove profile of the microgroove structure to be produced. The invention also relates to a method for producing a microgroove structure in a bore.
