Abstract (en)
[origin: WO2020160983A1] A honing tool (100) for processing an inner surface of a bore in a workpiece by the means of at least one honing operation comprises a tool body (110), which defines a tool axis (112); a first cutting group (160-1) attached to the tool body and having a plurality of radially adjustable first carriers (150-1), which are adjustable radially in relation to the tool axis (112) by means of an associated first cutting group adjustment system (170-1), each first carrier on its radial outer side covering a peripheral angular range of at least 20° and on the outer side (154) carrying a single first cutting material body, which is broad in the peripheral direction, or a plurality of narrow first cutting material bodies (140-1), which are arranged at a mutual distance from one another; and a second cutting group (160-2) which is attached to the tool body and has a plurality of radially adjustable second carriers (150-2), which are adjustable radially in relation to the tool axis (112) by means of an associated second cutting group adjustment system (170-2) independently of the first carriers (150-1), each second carrier (150-2) carrying an individual narrow second cutting material body (140-1, 140-2) on its radial outer side (154). All cutting material bodies (140-1, 140-2) of the first and second cutting group are arranged in an axially short cutting region (130), which has a length, measured in the axial direction, which is substantially smaller than an effective outer diameter of the cutting groups when the cutting material bodies are fully retracted.
