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.
Claims22
A slotting cutter comprising a cutter portion affixed to a body portion;
- the body portion comprising a disk-like support member having an outer peripheral surface with a first diameter and a central portion provided with an adapter;
- the cutter portion comprising an annular ring having an inner surface with a second diameter and an outer portion provided with recesses;
- the first diameter being larger than the second diameter;
- the cutter portion being formed of a material having thermal expansion and contraction characteristics such that application of heat to the cutter portion thermally increases the second diameter, thus allowing the support member of the body portion to be positioned inside the cutter portion, and cooling the cutter portion causes thermal contraction in an amount sufficient to rigidly affix the cutter portion to the body portion, wherein
- the slotting cutter is provided with a securing arrangement for ensuring that the cutter portion is secured against movement relative to the body portion;
- the securing arrangement comprises at least two countersunk through bores extending from a front face of the support member to the outer peripheral surface of the support member that mate, when the body portion is positioned inside the cutter portion, with at least two depressions provided on the inner surface of the cutter portion and countersunk head screws screwed into the at least two countersunk through bores and engaging the at least two depressions, and
- each countersunk through bore has a longitudinal axis that makes an acute angle (α) with a normal to the front face of the support member.

A slotting cutter assembly comprising:
- a body portion comprising a support member having an outer peripheral surface with a first diameter and a central portion provided with an adapter;
- and
- a cutter portion comprising an annular ring having an inner surface with a second diameter and an outer portion provided with recesses, the first diameter being larger than the second diameter;
- wherein
- the slotting cutter assembly is adjustable between an unassembled position in which the body portion and cutter portion are separated from each other, and an assembled position in which the outer peripheral surface of the support member of the body portion is positioned inside the inner surface of the cutter portion,
- the slotting cutter is provided with a securing arrangement for ensuring that the cutter portion is secured against movement relative to the body portion;
- the securing arrangement comprises at least two countersunk through bores extending from a front face of the support member to the outer peripheral surface of the support member that mate, when the body portion is positioned inside the cutter portion, with at least two depressions provided on the inner surface of the cutter portion and countersunk head screws screwed into the at least two countersunk through bores and engaging the at least two depressions, and
- each countersunk through bore has a longitudinal axis that makes an acute angle (α) with a normal to the front face of the support member.
