Double-sided, indexable face milling insert

摘要

The invention relates to a double-sided, indexable face milling insert of the type that comprises uppersides and undersides (16A, 16B), a neutral plane parallel to the same as well as a plurality of alternately applicable cutting edges (11), which are formed along circumferential borderlines in transitions between a number of clearance surfaces (13, 15) and the upperside as well as the underside, and which individually include a chip-removing main edge (12) and a surface-wiping secondary edge (14), which - as viewed in planar view - forms an obtuse angle with the main edge. Between each pair of upper and lower secondary edges (14), there extends a corner surface (15) that serves as a clearance surface and connects to the secondary edges via part surfaces (151, 152), which - as viewed in side elevation - form an acute angle with individual reference planes parallel to the neutral plane.
