REINFORCED DOUBLE-SIDED CUTTING INSERT AND CUTTING TOOL WITH REINFORCED DOUBLE-SIDED CUTTING INSERT

摘要

A double-sided cutting insert 21 according to the present invention comprises two planes of primary surfaces and two primary rake surfaces 37 adjacent primary cutting edges 33 forming first angles And a center support surface 29 forming a second angle beta with the planes of the major surfaces. Each end surface further includes primary intermediate surfaces 41 between the primary rake surfaces and the center support surface. The primary intermediate surfaces extend along the center axis A of the aperture 35 and are generally perpendicular to the plane of the primary side surfaces when measured at a center plane CP, Forms third angles [gamma] with planes of major surfaces that are greater than and less than second angles [beta]. The present invention also relates to a cutting tool.;
