Title:
切削器具用の切削インサート
Document Type and Number:
Japanese Patent JP5926066
Kind Code:
B2
Abstract:
A cutting insert for a gear milling tool comprises an under side (21), an opposite upper side (22) that forms a chip surface and is parallel to an extension plane (p), a circumferential edge side (23) that connects the upper side and the under side. A centre axis (A) extends through the under side. A symmetry line (S) is perpendicular to the centre axis. A first cutting edge (24) comprises a primary main cutting edge (24'), a secondary main cutting edge (24") - which are symmetrical in respect of the symmetry line - and a transverse end cutting edge (24a) between the primary and the secondary main cutting edge. A normal to the extension plane (p) forms an acute clearance angle with the edge side (23) at least along the first cutting edge (24) so that the cutting insert (2) obtains a positive cutting geometry.
