Abstract
A machining tool for use in machine tools for rotating cutting operations has a main body, which can be rotated about a center axis and which is elongate in the direction of the center axis, at least one cutting element fastened to the main body and at least one chip removal channel, which extends along the main body outside of the center axis and which is bounded inwardly by a core of the main body, through which core the center axis passes. The chip removal channel is outwardly closed at least over a longitudinal section by an outer chip space wall adjoining the core.
Claims20
A machining tool for use in machine tools for rotating cutting operations, comprising:
- a main body extending in the direction of a center axis and rotatable about the center axis;
- a cutting element fastened to the main body;
- a chip removal channel extending along the main body outside of the center axis and bounded inwardly by a core of the main body through which the center axis passes;
- an outer chip space wall adjoining the core and closing a longitudinal section of the chip removal channel, wherein the outer chip space wall and at least part of the core are formed as an integral additive manufacturing component whereby the outer chip space wall and the at least part of the core are a single homogenous piece of material;
- a coolant channel passing through the core and having curved sections;
- and
- wherein the main body has a front end-wall that covers a cross-sectional region of the chip removal channel and the end wall delimits an end gap that opens into the chip removal channel.
