Embodiment Construction

[0046] figure 1 -3 shows the cutting insert 100 according to the first embodiment of the present invention.

[0047] The cutting insert comprises an insert body 101 formed to define an upper extending plane U 1 The upper side 102 and define the lower extension plane L 1 The lower side 103 of the lower extension plane L 1 Parallel to the upper extension plane U 1 . Central axis Z 1 extends vertically through the upper extension plane U 1 and lower extension plane L 1 , and the positive direction is defined as extending from the plane L below 1 to the upper extension plane U 1 . The terms "higher" and "lower" are hereinafter relative to the 1 The upper extension plane U 1 used. A central hole 104 extends through the parallel upper side 102 and lower side 103 and is aligned with the central axis Z 1 same center. Because the cutting insert 100 is double-sided and indexable to different indexed positions, the upper side 102 and the lower side 103 are formed identicall...

Abstract

The invention provides a metal cutting turning insert and a turning tool. The cutting insert (100) for turning comprising an upper side (102), a lower side (103), a clearance surface (105) connecting the upper side and the lower side, and an upper cutting edge (106). The upper cutting edge forms a primary edge portion (112) and a secondary edge portion (113) connected by a nose edge portion (114). On the upper side, a chip former (115) is formed, comprising a nose bottom surface (116) formed behind the nose edge portion, a primary main bottom surface (117) extending along the primary edge portion, and, between the nose bottom surface and the primary main bottom surface, a continuous primary elevated bottom surface (118) extending along the primary edge portion, having a lowest point lower than the level of the primary edge portion but higher than the lowest point of each of the nose bottom surface and the primary main bottom surface.

Description

technical field [0001] The invention relates to a cutting insert designed for chip-removing machining of metal workpieces by means of turning according to the preamble of claim 1 . The invention also relates to a turning tool comprising a tool body and at least one such cutting insert. Background technique [0002] US 2012 / 0198973 discloses an indexable cutting insert configured for machining metal workpieces by means of turning. The cutting insert includes a insert body having an upper side defining an upper extending plane and a lower side defining a lower extending plane parallel to the upper extending plane, wherein a central axis extends perpendicularly through the upper extending plane and the lower extending plane flat. A clearance surface extends around the perimeter of the blade body and connects the upper and lower sides. A cutting edge is formed between the clearance surface and the upper side and extends around the upper side. The cutting edge forms a main ed...
