Abstract
A slotting cutter and a method for constructing the slotting cutter. The slotting cutter is structurally divided into two portions, a central adapter portion and a cutter portion. The central adapter portion is a disk with an F-type or S-type adapter. The cutter portion is an annular ring provided with cutting insert receiving pockets, or cartridge receiving pockets. The cutter portion and a body portion are manufactured separately and combined to form the slotting cutter by a heat shrinkage method.
Claims39
A method for assembling a metal-cutting slotting cutter comprising:
- providing a body portion comprising a disk-like support member having a front face, an outer peripheral surface with a first diameter, and a central portion;
- providing a cutter portion comprising an annular ring having an inner surface with a second diameter and an outer portion provided with recesses;
- positioning the body portion inside the cutter portion;
- and
- inserting at least one screw into the front face of the support member, at an acute angle (α) with respect to a normal to the front face, such that the screw emerges from the outer peripheral surface of the support member and engages a depression formed in the cutter portion, to thereby help secure the support portion to the cutter portion.
A method for assembling a metal-cutting slotting cutter comprising:
- providing a body portion comprising a disk-like support member having a front face, an outer peripheral surface with a first diameter, and a central portion;
- providing a cutter portion comprising an annular ring having an inner surface with a second diameter and an outer portion provided with recesses;
- aligning a protrusion protruding from the outer peripheral surface of the support member with an indent formed on the inner surface of the cutter portion;
- inserting the outer peripheral surface of the body portion into the annular ring of the cutter portion to thereby position the body portion inside the cutter portion;
- and
- inserting a securing member into at least one bore formed in the support member to thereby help secure the support portion to the cutter portion, said at least one bore having a longitudinal axis that extends at an angle oblique to a rotary axis (R) of the body portion.

- providing a body portion comprising a disk-like support member having a front face, an outer peripheral surface with a first diameter, and a central portion;
- providing a cutter portion comprising an annular ring having an inner surface with a second diameter and an outer portion provided with recesses;
- applying heat to the cutter portion to thereby cause an expansion of the annular ring;
- aligning a protrusion protruding from the outer peripheral surface of the support member with an indent formed on the inner surface of the cutter portion;
- inserting the outer peripheral surface of the body portion into the annular ring of the cutter portion to thereby position the body portion inside the cutter portion;
- and
- inserting a securing member into at least one bore formed in the support member to thereby help secure the support portion to the cutter portion, said at least one bore having a longitudinal axis that extends at an angle oblique to a rotary axis (R) of the body portion.
