Problems solved by technology

[0007] However, in the conventional cutting insert, even if the cutting edge portion is provided on both opposite ends of the cutting insert, since the cutting insert is mounted on the cutter body in only one direction, the cutting edge portion is only partially The corner blade (corner blade) or main cutting edge is used to cut the workpiece
Therefore, there is a problem that the service life of the cutting insert is shortened

Embodiment Construction

[0012] The present invention provides a milling cutter comprising: a cutter body equipped with a plurality of insert seats; and a cutting insert having a hexahedral shape embedded and fixed in each of two directions. on the base of an insert.

[0013] In addition, the cutting insert has: a through hole formed in the cutting insert from the upper surface to the lower surface of the cutting insert; on the first and second ends of the piece.

[0014] In addition, insert seats are formed radially inwardly around the circumferential outer surface of the cutter body and are spaced apart from each other at regular intervals, each insert seat including a groove formed on the first and second inner surfaces of the insert seat, respectively. First and second locking holes, so that the cutting insert can be fixed on the insert base by a locking screw, which is fastened to the first or second locking hole of the insert base after passing through the through hole of the cutting insert mi...

Abstract

It is an object of the present invention to provide a milling cutter comprising a cutting insert (120) and a cutter body (110), wherein the cutting insert has a hexahedral shape and is provided with first and second cutting edges on opposite ends thereof The cutter body is provided with a plurality of insert seats (112) in which the cutting inserts (120) are placed and fixed thereon in either direction. The cutting inserts (120) can be secured to the associated insert bases (112) in a selected orientation such that all corner or main cutting edges provided on the first and second cutting edge portions of the cutting inserts can be used. for machining workpieces. Thus, the present invention extends the useful life of the cutting insert (120).

Description

technical field [0001] The present invention relates generally to a milling cutter, and more particularly to a milling cutter comprising a cutting insert having a cubic or rectangular parallelepiped shape with first and The second cutting edge portion, the cutter body is provided with a plurality of insert seats in which the cutting inserts are seated and fixed in either direction, so that the cutting inserts can be fixed in either direction on the associated On the insert base, all corner or main cutting edges thus arranged on the first and second cutting edge portions of the cutting insert can be used for machining the workpiece, thereby prolonging the service life of the cutting insert. Background technique [0002] Generally, cutting tools can be used to machine various workpieces, for example, the cutting tool is mounted on a machine tool, and then a cutting operation is performed to form the workpiece into a desired shape. [0003] In general, a cutting tool includes ...
