Estimating the term…
The invention relates to a tool for machining sliding surfaces of a bearing shell (30), comprising a rotary drive for driving a drilling spindle (20) that can be rotated about a rotational axis and at least one first cutting cartridge that is mounted on the drilling spindle (20) in order to cut the bearing shell (30) to a certain wall thickness by rotating the drilling spindle (20). The tool is characterised in that the first cutting cartridge can be adjusted by an adjustment means in a direction of adjustment that has a component in the radial direction of the drilling spindle, while the drilling spindle (20) is rotated by the rotary drive. The invention further relates to a bearing shell (30) comprising a deliberately structured sliding surface (31) and to a method for producing a bearing shell (30) comprising a deliberately structured sliding surface (31).
