Problems solved by technology

In conventional indexable cutting inserts, it necessarily has the consequence that the locating and support surfaces over which the indexable cutting insert is fixed to the indexable cutting cartridge holder are positioned such that at the corresponding working cutting edge above, relatively unfavorable leverage conditions act on the blade, which lead to the blade being pried out of its pocket or can at least cause a small change in the position of the blade, so that the position of the cutting edge is also not defined with sufficient precision

Embodiment Construction

[0056] The indexable cutting insert has four cutting edges 4a, 4b, 4c and 4d, in figure 1 The four cutting edges extend perpendicular to the plane of the paper. These four cutting edges define the corners of an imaginary quadrilateral, in particular a rectangle, drawn by dashed lines and comprising long sides 13 and short sides 14 . The actual peripheral surfaces 16a, 16b, 16c and 16d always extending between the cutting edges 4a, 4b, 4c and 4d follow paths deviating from the straight sides 13 and 14 in the form of portions angled relative to each other, so The peripheral surface protrudes partially convexly beyond the side 14 on the short side 14, but is again concave in the center and has positioning notches 5a, 5b there. Peripheral surfaces 16a and 16c extending along the long side 13 are also recessed relative to the long side 13 so as to form substantially triangular cutting tips 1a, 1b, 1c and 1d in plan view from The main part 1 of the body protrudes toward the corner...

Abstract

The present invention relates to an indexable cutting insert comprising a plate-shaped body having two parallel main surfaces and a peripheral surface connecting the two main surfaces and comprising Angled portions, wherein four cutting edges extending transversely to the main surface are arranged on the peripheral surface at the transitions of the portions of the peripheral surface that are angled relative to each other, and in plan view of the main surface, the cutting edges The position bounds the quadrilateral. In order to provide indexable cutting inserts and associated indexable cutting cartridge holders, which can be secured by more favorable leverage and moreover allow permanently more precise positioning of the cutting edges, it is proposed according to the invention that the quadrilateral always have two short sides and two long sides, and the cutting edges are always oriented in opposite directions in the circumferential direction at adjacent corners of the quadrilateral, and always oriented in the same direction at diagonally opposite corners of the quadrilateral .

Description

technical field [0001] The invention relates to an indexable cutting insert for grooving or parting off, comprising a plate-shaped body with two parallel main surfaces and a peripheral surface connecting the two main surfaces and comprising portions angled relative to each other, wherein four cutting edges extending transversely to said main surfaces are arranged on the peripheral surface at the transitions of the portions of the peripheral surface angled relative to each other , and wherein, in plan view of the main surface, the position of the cutting edge defines a quadrilateral. [0002] The invention also relates to an indexable cutting insert holder for an indexable cutting insert of the type described above, the indexable cutting insert holder having an insert sleeve and a side surface, and having a recess adjoining said side surface, the recess There are faces extending generally perpendicular to the side surfaces and angled relative to each other.
