Abstract
A tool body for a milling tool includes a front end and a rear end between which a center axis and a peripheral envelope surface extend. The tool body is arranged to be rotated in a direction of rotation around the center axis. At least one insert seat is configured to support a cutting insert. A chip pocket is provided in front of the insert seat in the direction of rotation, delimited by a wall surface. A surface pattern including a plurality of first grooves and second grooves is formed on at least a portion of the wall surface. The second grooves intersect the first grooves and each groove of the first grooves and/or each groove of the second grooves has a concave groove profile.
Claims21
A tool body for a milling tool, the tool body comprising:
- a front end and a rear end between which a centre axis and a peripheral envelope surface extend, the tool body being configured to be rotated in a direction of rotation around the centre axis;
- at least one insert seat formed in a transition between the front end and the peripheral envelope surface, wherein the insert seat is configured to support a cutting insert arranged to be mounted therein;
- a chip pocket provided in front of the insert seat in the direction of rotation, wherein the chip pocket is delimited by a wall surface;
- and
- a surface pattern included in the wall surface of the chip pocket, the surface pattern including a plurality of first concavely curved grooves forming a ridge extending along at least two neighbouring first concavely curved grooves and a plurality of second concavely curved grooves formed at the ridge of the at least two first concavely curved grooves,
- wherein each of the first concavely curved grooves extends along a first length extension direction and each of the plurality of second concavely curved grooves extends along a second length extension direction, different from the first length extension direction, such that the plurality of second concavely curved grooves intersect the plurality of first concavely curved grooves,
- wherein each groove of the plurality of first concavely curved grooves and each groove of the plurality of second concavely curved grooves has a concave groove profile, and
- wherein the concave groove profile is arc shaped.
A tool body for a milling tool, the tool body comprising:
- a front end and a rear end between which a centre axis and a peripheral envelope surface extend, the tool body being configured to be rotated in a direction of rotation around the centre axis;
- at least one insert seat formed in a transition between the front end and the peripheral envelope surface, wherein the insert seat is configured to support a cutting insert arranged to be mounted therein;
- a chip pocket provided in front of the insert seat in the direction of rotation, wherein the chip pocket is delimited by a wall surface;
- and
- a surface pattern included in the wall surface of the chip pocket, the surface pattern including a plurality of first grooves and a plurality of second grooves,
- wherein each of the plurality of first grooves extends in a first length extension direction, each of the plurality of second grooves extends in a second length extension direction, and the first length extension direction is different from the second length extension direction such that the plurality of second grooves intersect the plurality of first grooves,
- wherein each groove of the plurality of first grooves and each groove of the plurality of second grooves has a concave groove profile that is arc shaped,
- wherein the plurality of first grooves includes two neighbouring first grooves that are adjacent to each other and separated by a ridge, and
- wherein two neighbouring second grooves of the plurality of second grooves are separated in the first length extension direction by a distance along the ridge such that the two neighbouring second grooves of the plurality of second grooves are connected by a portion of the ridge.
