Abstract
An arcuate cutting tool part for a machining device for cutting flat material, such as sheet metal, is disclosed. The arcuate cutting tool part comprises a radially outer cutting edge area having at least one first arcuate cutting edge, an attachment arrangement for attachment to the machining device, a first coupling arrangement having a first coupling portion, and a second coupling arrangement having a second coupling portion, wherein the arcuate cutting tool part defines a circumferential direction in accordance with the arcuate shape, and wherein the first and/or the second coupling arrangements are configured to be releasably coupled to at least one further arcuate cutting tool part in the circumferential direction.
Claims19
An arcuate cutting tool part for a machining device for cutting flat material, such as sheet metal, comprising:
- a radially outer cutting edge area having at least one arcuate cutting edge;
- an attachment arrangement for attachment to the machining device;
- a first coupling arrangement having a first coupling portion;
- and
- a second coupling arrangement having a second coupling portion,
- wherein the arcuate cutting tool part defines a circumferential direction in accordance with an arcuate shape of the arcuate cutting tool part, and
- wherein at least one of the first and the second coupling arrangements are configured to be releasably coupled to at least one further arcuate cutting tool part in the circumferential direction.
An arcuate cutting tool for a machining device for cutting flat material, the arcuate cutting tool comprising:
- a first cutting tool part, comprising:
- a first radially outer cutting edge area having at least one first arcuate cutting edge;
- a first attachment arrangement for attachment to the machining device;
- and
- a first set of coupling arrangements,
- wherein the first arcuate cutting tool part defines a first circumferential direction in accordance with a first arcuate shape of the first cutting tool part, and
- a second cutting tool part, comprising:
- a second radially outer cutting edge area having at least one second arcuate cutting edge;
- a second attachment arrangement for attachment to the machining device;
- a second set of coupling arrangements,
- wherein the second arcuate cutting tool part defines a second circumferential direction in accordance with a second arcuate shape of the second cutting tool part, and
- wherein a coupling arrangement of the second set of coupling arrangements is coupled to a coupling arrangement of the first set of coupling arrangements.
A machining device for cutting flat material, comprising:
- a base including a support table for the flat material, the base defining a feed direction in which the flat material can be fed into the machining device;
- and
- a cutting device arrangement configured to cut the flat material, comprising:
- a radially outer cutting edge area having at least one arcuate cutting edge;
- an attachment arrangement for attachment to the machining device;
- a first coupling arrangement having a first coupling portion;
- and
- a second coupling arrangement having a second coupling portion,
- wherein the cutting device arrangement defines a circumferential direction in accordance with an arcuate shape of the cutting device arrangement, and
- wherein at least one of the first and the second coupling arrangements are configured to be releasably coupled to another cutting device arrangement in the circumferential direction.
