Abstract (en)
[origin: WO2022167205A1] The invention relates to a honing bar (200) for use in a honing tool for processing the inner surface of a bore, comprising a cutting layer carrier (202) which carries a cutting layer (210) on an outer side, which cutting layer has cutting grains (215) bound within a binding (213) and an abrasive work surface (220) for engaging on the inner surface of the bore. The honing bar (200) defines a longitudinal direction (L) to be oriented parallel to a bore axis. The work surface (220) extends in a width direction (B), perpendicular to the longitudinal direction, between a first lateral surface (212-1) and a second lateral surface (212-2) of the cutting layer. The work surface (220) has a generally convex macroscopic design having at least two macroscopically flat facets (230-1, 230-2, 230-3) of different orientation which transition along edges (235-1 to 235-4) extending in the longitudinal direction to an adjacent facet or a lateral surface.
