Abstract
A rotary slitter includes a disc-shaped rotary slitter body having a rotation axis, opposing first and second surfaces, a circumferential surface connecting the first and second side surfaces, and a cutting portion. The cutting portion includes an insert seating construction, a groove formed in the first surface and surrounding the insert seating construction, in a view of the first surface along the rotation axis, and a positioning hole. The rotary slitter further includes a positioning screw mounted to the positioning hole and configured to adjust a position of a cutting edge of a cutting insert mounted to the insert seating construction.
Claims21
A disc-shaped rotary slitter body configured to rotate about an axially extending rotation axis AR and comprising:
- opposing first and second surfaces oriented perpendicular to the rotation axis AR;
- a circumferential surface connecting the first and second surfaces;
- and
- a cutting portion located at the circumferential surface;
- the cutting portion comprising:
- a cutting insert seating construction;
- a groove surrounding the cutting insert seating construction in a view of the first surface along the rotation axis AR;
- and
- a positioning hole opening out towards the first surface;
- wherein:
- the groove extends from a first groove end at a rotationally trailing side to a second groove end at a rotationally leading side, of the cutting insert seating construction of the cutting portion.
A disc-shaped rotary slitter body configured to rotate about an axially extending rotation axis AR and comprising:
- opposing first and second surfaces oriented perpendicular to the rotation axis AR;
- a circumferential surface connecting the first and second surfaces;
- and
- a cutting portion located at the circumferential surface;
- the cutting portion comprising:
- a cutting insert seating construction;
- a groove surrounding the cutting insert seating construction in a view of the first
- surface along the rotation axis AR;
- and
- a positioning hole opening out towards the first surface;
- wherein
- the groove comprises a through-groove portion which is devoid of groove web material between the first and second surfaces and the clamping hole is formed at the through-groove portion.
