Abstract
A rotating tool mateable with the spindle of a machine tool for high speed rotation is disclosed. The tool is comprised of a shank and a disk. The disk has attached to its periphery cutting inserts. These inserts may be attached directly to recesses in the disk or to lugs protruding from the disk. If the inserts are attached to lugs, then the disk will further have opposing counterweight lugs protruding from the disk in an opposite direction. A band of high tenacity material extends around the disk to restrain radial expansion. Additionally, the disk may be encompassed in a restraining material to restrain any disk parts that may separate from the disk body.
Claims28
A rotating tool mateable with the spindle of a machine tool for high speed rotation about a longitudinal axis comprised of:
- a) a shank mountable within the spindle;
- b) a disk symmetric about the longitudinal axis, connected to the shank and having a central hub and an outer periphery;
- c) cutting inserts symmetrically attached to the periphery of the disk;
- and
- d) a separate band of high tenacity material about the perimeter of the disk to restrain expansion from centrifugal forces on the disk.

- a) a shank mountable within the spindle;
- b) a disk symmetric about the longitudinal axis, connected to the shank and having a central hub and an outer periphery;
- c) a series of insert lugs protruding longitudinally from the outer periphery of the disk and symmetrically disposed about the periphery of the disk;
- d) cutting inserts attached to each insert lug;
- e) a series of counterweight lugs longitudinally protruding from the outer periphery of the disk in a direction opposite to that of the insert lugs;
- f) a separate band of high tenacity material about the perimeter of the disk to restrain expansion from centrifugal forces on the disk;
- and
- g) a sheath encompassing the top and sides of the disk and a portion of the bottom of the disk leaving the cutting inserts uncovered.
