Schneideinsatz und Fräswerkzeug

摘要

A cutting insert (20, 40), especially a cutting insert with a rectangular basic shape, which can be fitted at a radially negative ( gamma f) and an axially positive ( gamma p or gamma pal) tool orthogonal rake in a milling cutter (35), the cutting edges of which, extending between adjacent cutting corners (21 to 24), have a main cutting section (25), a face cutting section (27) and a transitional region (26) between them, in which the main cutting section (24, 42) is inclined at a negative angle ( lambda ) to the cutting insert fitting surface (33) so that at least one point (30), lying near the transition region (26) on the main cutting section (25), projects by one height unit (H) beyond the face cutting section (27).
