Milling tool and method for producing a rolling bearing cage
A milling tool includes a main body and a plurality of cutting inserts with respective cutting edges. The main body has an end face and a barrel-shaped curved lateral face. A first group of the plurality of cutting inserts are fastened on the end face, a second group of the plurality of cutting inserts are fastened on the barrel-shaped curved lateral face, and the respective cutting edges describe a barrel shape. Each one of the plurality of cutting inserts may be designed as an indexable insert.
1. A milling tool comprising:
a main body comprising:
a flat end face; and
a curved lateral face;
a plurality of cutting inserts comprising respective cutting edges, wherein:
a first group of the plurality of cutting inserts are fastened on the end face;
a second group of the plurality of cutting inserts are fastened on the curved lateral face; and
respective surfaces of each of the first group of the plurality of cutting inserts facing the flat end face are arranged at an angle relative to the flat end face.
2. The milling tool of claim 1 wherein each one of the plurality of cutting inserts is designed as an indexable insert.
3. The milling tool of claim 1 wherein each one of the plurality of cutting inserts in the second group of the plurality of cutting inserts is fixed with an unchangeable setting on the curved lateral face.
4. The milling tool of claim 1 further comprising a rotational axis, wherein the flat end face is orthogonal to the rotational axis.
5. The milling tool of claim 1 further comprising a rotational axis, wherein the respective cutting edges of the first group of the plurality of cutting inserts define a plane orthogonal to the rotational axis.
6. The milling tool of claim 5 , wherein respective surfaces of each of the first group of the plurality of cutting inserts facing the flat end face are arranged at an angle relative to the flat end face.
7. The milling tool of claim 1 wherein each one of the first group of the plurality of cutting inserts has a parallelogram shape.
8. The milling tool of claim 1 wherein each one of the second group of the plurality of cutting inserts has a parallelogram shape.
9. The milling tool of claim 1 wherein a diameter of the curved lateral face decreases as the curved lateral face approaches the flat end face.
10. A milling tool comprising:
a rotational axis;
a main body comprising:
a flat end face; and
a curved lateral face; and
a plurality of cutting inserts comprising respective cutting edges, wherein:
a first group of the plurality of cutting inserts are fastened on the end face;
a second group of the plurality of cutting inserts are fastened on the curved lateral face;
the respective cutting edges of the first group of the plurality of cutting inserts define a plane orthogonal to the rotational axis; and
respective surfaces of each of the first group of the plurality of cutting inserts facing the flat end face are not coplanar with the flat end face.
