Abstract
A cutting tool, in particular for machining metal, is described. It comprises a tool main body that has at least one interface for receiving a cutting insert that can be attached to the tool main body. At least one cooling duct is provided in the tool main body and has, at its end on the interface side, an outlet section with an elongate outlet cross-section on the interface side. The tool main body is manufactured at least in sections by means of a generative manufacturing process. A method for manufacturing such a cutting tool is also presented.
Claims17
A cutting tool with a tool main body comprising:
- at least one interface for receiving a cutting insert for attachment to the tool main body, the cutting insert having at least one cutting edge, wherein at least one cooling duct is provided in the tool main body and the cooling duct comprises, at an end for expelling coolant directly to the cutting insert, an outlet section with a substantially rectangular or arc-shaped outlet cross-section above the interface, wherein the tool main body is manufactured at least in sections by means of an additive manufacturing process, and wherein a length of a side of the rectangular outlet cross-section or an arc length substantially corresponds to a length of the at least one cutting edge.
A cutting tool with a tool main body comprising:
- at least one interface for receiving a cutting insert for attachment to the tool main body, the cutting insert having at least one cutting edge, wherein at least one cooling duct is provided in the tool main body and the cooling duct comprises, at an end for expelling coolant, an outlet section with an elongate outlet cross-section, the elongate outlet cross-section above the interface and tangential to rotation of the tool main body during a cutting operation, and wherein the tool main body is manufactured at least in sections by means of an additive manufacturing process, and wherein a length of a side of the elongate outlet cross-section substantially corresponds to a length of the at least one cutting edge.
