Embodiment Construction

[0029] Hereinafter, preferred embodiments of the cutting insert according to the present invention will be described in detail with reference being made to different drawings. First, the milling body or base body cooperating with the cutting insert will be described in more detail, and then the cutting insert itself will be described.

[0030] The assembled milling cutter tool shown in Figures 1-4 comprises a base body 1 and a plurality of cutting inserts 2, only one of which is shown in the respective figure. The basic body or milling cutter body 1 is rotatable about a central axis marked C in a direction of rotation R and has a rotationally symmetrical envelope surface 3 and a front face 4 . A plurality of chip pockets 5 are opened in the envelope surface and the front face, each of said plurality of chip pockets 5 comprising a seat 6 for receiving a cutting insert 2 . In the example, the number of flutes and cutting inserts are three each.

[0031] In this case, the seat ...

Abstract

An indexable end-milling insert of the following type includes an underside (14), an upperside (13) and a plurality of cutting edges that are formed between the upperside and a number of clearance sides and that include a chip-removing main edge (18) as well as a surface-wiping wiper edge (19). The cutting insert has a square basic shape and includes four main edges (18) and four wiper edges (19) that are countersunk to a lower level than the main edges. The wiper edge (19) is included in a lip (31) projecting in relation to a secondary clearance surface (26) and has a tertiary clearance surface (32), which laterally transforms into a primary clearance surface (22). The primary clearance surface (22) has a width that decreases from the two opposite ends (38, 39) thereof toward a section(40) having a smallest width therebetween.

Description

technical field [0001] The present invention relates to an indexable end milling insert of the type comprising a lower side, an upper side and a plurality of cutting edges formed between the upper side and a plurality of clearance sides and comprising respectively a chip-removing main edge and a surface-wiping wiping edge that transitions via a corner of the cutting insert into a main edge extending arcuately between a first end and an opposite second end, the main edge The second end is at a higher height relative to the underside than the first end, and the main edge is bounded between a chip surface and a convexly arched main clearance surface, wherein the chip surface is within the cutting edge line, Instead, the primary clearance surface lies outside the cutting edge line and there is a secondary clearance surface below the primary clearance surface. Background technique [0002] A cutting insert of the above-mentioned type for end milling is previously known from EP 0...
