Abstract
A cutting tool includes a cutting insert and a tool holder. The tool holder includes: a base for supporting a bottom surface of the cutting insert; a clamping arm for pressing a top surface of the cutting insert; an insert receiving space formed between the bottom surface of the clamping arm and the base; and a supporting surface which defines an end of the insert receiving space and supports an end of the cutting insert. The cutting insert includes: a first pressing region on the front portion of the top surface which is oriented in a vertically upward direction; and a second pressing region on the rear portion of the top surface which is oriented at an angle in the front direction.
Claims12
A cutting tool, comprising:
- a cutting insert comprising a first pressing region on a front portion of a top surface oriented in a vertically upward direction, and a second pressing region on a rear portion of the top surface oriented at an angle in a front direction;
- and
- a tool holder comprising a base for supporting a bottom surface of the cutting insert, a clamping arm for pressing the top surface of the cutting insert, an insert receiving space formed between a bottom surface of the clamping arm and the base, and a supporting surface defining an end of the insert receiving space and supporting an end of the cutting insert;
- wherein a front portion of the clamping arm mates with the first pressing region, while a rear portion of the clamping arm comprises a projection on the bottom surface formed to be mated with the second pressing region, and
- wherein the front portion of the clamping arm presses the first pressing region in the vertically downward direction and the projection of the clamping arm presses the second pressing region in the angled direction toward the tool holder.
A double-ended cutting insert, comprising:
- an elongated insert body having a top surface, a bottom surface and first and second ends;
- first and second sets of pressing regions formed on the top surface of the cutting insert;
- each set of pressing regions comprising, from a given end, a first pressing region on a front portion of the top surface oriented in a vertically upward direction, and a second pressing region on a rear portion of the top surface oriented at an angle in a front direction;
- wherein the first and second sets of pressing regions are symmetrically formed on the top surface of the cutting insert, such that the cutting insert is rotationally symmetric about a central axis.
