Problems solved by technology

However, the milling insert is not optimized with regard to ease of production
Furthermore, the geometry of the milling insert does not allow adaptation of the cutting edge and clearance face to different milling conditions
Typically the main clearance behind the main cutting edge will vary along the main cutting edge resulting in irregular wear of the cutting edge and varying edge strength along the main cutting edge

Embodiment Construction

[0037] Figure 1-10 Different views of a milling insert 100 for shoulder milling (ie milling with an entry angle of 90°) according to an embodiment of the invention are shown. The milling insert 100 can be indexed with two index positions and has a positive basic shape. It comprises an upper side 101 and a lower side 102 opposite the upper side 101 . The central axis C1 extends between the upper side 101 and the lower side 102 . A central hole is provided for mounting the milling insert in the tool body. The upper side 101 includes a rake face 103 having a planar central region 120 extending around the central bore. The underside 102 includes a planar counter surface 105 . The flank face 104 extends around the periphery of the milling insert. The cutting edge 106 is formed between the rake face 103 and the flank face 104 . Upper extension plane P U is defined to extend parallel to the bed face 105 at the level of the cutting edge 106 . The cutting edge 106 and the uppe...

Abstract

A milling insert (100) for shoulder milling having a positive basic shape and comprising an upper side (101) comprising a rake surface (103), a lower side (102) comprising a planar bottom surface (105), a side surface (104) extending around the periphery of the milling insert, and a cutting edge (106) formed between the side surface and the rake surface. The cutting edge comprises at least a major cutting edge portion (107a, 107b), a corner radius cutting edge portion (108a, 108b), a ramping cutting edge portion (110a, 110b), and a surface wiping cutting edge portion (109a, 109b). The side surface comprises an upper set of primary clearance surfaces (111b) and a lower set of secondary clearance surfaces (115b) comprising a plurality of planar secondary clearance surfaces (115b), wherein the upper set of primary clearance surfaces forms an overhang protruding with respect to the secondary clearance surfaces and extending around the entire upper periphery of the milling insert.

Description

technical field [0001] The invention relates to a milling insert for shoulder milling according to the preamble of claim 1 . The invention also relates to a milling tool according to claim 16 . Background technique [0002] Milling tools for shoulder milling, such as shank end milling tools, can advantageously be used for machining shoulders, grooves and edges. For machining of dimples and the like, it is preferable to use a milling tool having a ramping cutting edge portion that is closer to the central axis of the milling tool than the main cutting edge portion used in machining The cutting edge portion is formed at an angle relative to the surface wiping cutting edge portion. For cost-effectiveness, it is preferred to use a milling tool comprising on the one hand a tool body and, on the other hand, detachable and replaceable milling inserts. [0003] US 2006 / 0013661 discloses a milling insert and a milling tool intended for shoulder milling. The milling insert is inde...
