Embodiment Construction

[0030] Aspects of the invention will now be described more fully. The same reference numbers refer to the same elements throughout. Well-known functions or constructions may not be described in detail for brevity and / or clarity.

[0031] Figures 1a-1e Different views of a cutting insert 2 of a milling cutter according to an embodiment are shown. The cutting insert 2 includes an insert body 4 having a central longitudinal axis 6 extending in the longitudinal direction of the insert body 4 . An imaginary central plane 8 including the central longitudinal axis 6 extends centrally through the blade body 4, see Figure 1c and Figure 1d . The blade body 4 is generally defined by a top surface 10 , a bottom surface 12 , and a circumferential surface 14 extending circumferentially around the blade body 4 between the top surface 10 and the bottom surface 12 . The top surface 10 and the bottom surface 12 extend substantially on opposite sides of the central plane 8 in the longitu...

Abstract

A cutting insert (2) is disclosed herein. The cutting insert (2) comprises an insert body (4) having a central longitudinal axis. The blade body (4) comprises a first radial side and a second radial side. The first axial side (20a) includes a first relief surface (22a), a second relief surface (22b), and a first recess (24a) having a first bottom surface (26a). Said first relief surface (22a), second relief surface (22b) and first recess (26a) are arranged such that each point of them can be viewed from a first side view towards a first radial side or Seen from a second side view towards the second radial side, and such that the blade body (4) in the longitudinal direction is at a central portion towards said central longitudinal axis (6) more than towards said first radial side (18a ) or the outer portion of one of the second radial side (18b) is longer. The paper also discloses a milling cutter.

Description

technical field [0001] The present invention relates to a cutting insert for a milling cutter and a milling cutter including the cutting insert. Background technique [0002] Milling cutters are rotary cutting tools that can be provided with one or more cutting inserts. A face mill is a special type of milling cutter that is constructed for "facing", ie, milling of flat surfaces. [0003] US 2013 / 0045061 discloses a cutting insert for a rotary cutting tool. The cutting insert includes an upper surface, a lower surface and a side surface connected to each of the upper and lower surfaces. The cutting insert can be indexed four times in the cutting tool. A cutting edge extends at the intersection between the upper surface and the side surface and includes a first cutting edge, a corner cutting edge, and a second cutting edge. Along the side surface, a constraining portion including a flat surface shaped portion extends around the cutting insert. The cutting inserts are sha...
