Abstract
A cutting insert which is suitable for high cutting speed, a tool body thereof and a tool are provided. A tool according to the present invention is a tool in which a leading end thereof is provided with a force transmitting portion and for which a rotational axis extending from the leading end to a base end thereof is defined, wherein the tool comprises a cam portion which is arranged closer to the base end than the force transmitting portion and for which a dimension from the rotational axis of the tool varies in accordance with an angle at which the cam portion is rotated around the rotational axis.
Claims19
A tool in which a leading end thereof is provided with a force transmitting portion and for which a rotational axis extending from the leading end to a base end thereof is defined,
- wherein the tool further comprises a cam portion which is arranged closer to the base end than the force transmitting portion, and
- the cam portion including an outer peripheral surface having a radius that varies constantly around the entire outer peripheral surface.
An adjustment mechanism for adjusting a position of a cutting edge of a cutting insert which is removably mounted on an insert mounting part of a tool body or a cartridge in a cutting tool, the adjustment mechanism comprising:
- a tool for which a rotational axis extending from a leading end thereof to a base end thereof is defined, the tool comprising a cam portion including an outer peripheral surface having a radius that varies constantly around the entire outer peripheral surface;
- and
- an engagement part which is provided so as to be adjacent to the insert mounting part or the cartridge in the tool body and which is configured so as to be capable of being engaged with the tool such that the tool is capable of being rotated around the rotational axis,
- wherein, in a state in which the cutting insert or the cartridge is arranged so as to be movable, the tool is rotated in the engagement part around the rotational axis, whereby the cam portion acts so as to move the cutting insert or the cartridge.
A tool body of a cutting tool comprising an insert mounting part on which a cutting insert is removably mounted, the tool body comprising
- an engagement part which is capable of being engaged with a tool such that the tool having a force transmitting portion for imparting a force to a fixing member which is mounted on the tool body so as to fix the cutting insert to the insert mounting part is capable of being rotated around the rotational axis, the tool comprising a cam portion for which a dimension from an outer peripheral surface of the tool to the rotational axis extending from a leading end of the tool to a base end thereof varies in accordance with an angle at which the cam portion is rotated around the rotational axis, the cam portion being closer to the base end than the force transmitting portion,
- wherein, in a state in which the cutting insert is arranged so as to be movable in the insert mounting part, the tool is rotated in the engagement part around the rotational axis, whereby the cam portion acts so as to move the cutting insert.
