Abstract

The present invention relates to a cutting tool suitable for detachably attaching a cutting insert to an insert seat by screwing a fastening screw through a through hole of the cutting insert into a threaded hole of the insert seat of a tool body. Assembly device. The central axis of the threaded hole is inclined relative to the normal direction of the bottom wall surface of the blade mounting seat. When the cutting insert is placed on the insert mounting seat, the central axis of the threaded hole extends from the central axis of the through hole to one of the two side wall surfaces of the insert mounting seat on an imaginary plane defined by expanding the bottom wall surface. offset. On this imaginary plane, the centripetal direction of the central axis of the threaded hole is different from the inclination direction of the central axis of the threaded hole.

Description

technical field [0001] The present invention relates to a cutting tool, and more particularly, to an assembly device for a cutting tool for detachably assembling a cutting insert, a tool body, and a cutting tool. Background technique [0002] There are various configurations of mounting devices for cutting tools in which cutting inserts are mounted to a tool body using fastening screws. The mounting device exemplified here refers to a mounting structure in which the insert mounting seat of the tool body has a threaded hole capable of threading engagement with a fastening screw inserted through the through hole of the cutting insert. [0003] For example, Patent Document 1 discloses a cutting tool in which, in an insert mounting seat having a bottom wall and two side walls, a fastening screw is screwed into a threaded hole in the bottom wall through a through hole of the cutting insert. The cutting insert is detachably fixed. In the assembling device of the cutting tool, th...
