Problems solved by technology

Therefore, when using notched cutting inserts, it is always necessary to prepare multiple types of inserts, leading to an increase in storage costs
In addition, although it is said to be a blade of another shape, the difference is very small, so there is a possibility that a blade other than the type that should be mounted is installed incorrectly, etc.

Abstract

Provided are a cutting insert suitable for pocket machining of metal molds and the like, and an indexable cutting tool that uses the cutting insert. The cutting insert (10) is provided with: a rake face (14); a flank face (15); and a major cutting edge (11) that is formed on the intersecting ridge of the rake face (14) and the flank face (15), and that extends in the direction that intersects with the cutting direction of the rotary cutting tool. At least one partitioning section (12) that is not involved in cutting is provided in the middle of said major cutting edge (11) in a direction along the major cutting edge (11). The major cutting edge (11) is composed of two first cutting edges (11a) and second cutting edges (11b) separated by the partitioning section (12), and is configured in such a manner that, when the cutting insert is attached to the tool body (1) of the cutting tool, the cutting angles ([kappa]1, [kappa]2) between the first cutting edge (11a) and the second cutting edge (11b) falls in a range of 5 DEG and 20 DEG .

Description

technical field [0001] The present invention relates to a cutting insert and an edge-replaceable turning tool equipped with the cutting insert. Background technique [0002] Conventionally, a turning tool capable of drilling has been used in recess processing in the manufacture of molds and the like. In recess processing, it is one of the conditions for efficient processing to continuously discharge generated chips from the processed recess (recess), and a blower is used for this purpose. In this discharge method, high-pressure air is sprayed onto the machined recess, and the cutting chips are blown out of the hole by the air pressure. [0003] When using a blower, it is not possible to spray high-pressure air to the extent that large chips can be blown away. Therefore, it is required to generate as fine chips as possible for a turning tool for machining recesses. As one of methods for achieving chip refinement, Patent Document 1 discloses a cutting insert in which a plura...
