DESCRIPTION OF EMBODIMENTS

[0074] With reference to the figures, some embodiments are now described in more detail, which is not intended, however, to limit the scope of the present application. The machine tool (2) causes the rotation of the rotating interface (5) of the coupling structure of the device (1), through the mechanical connecting chain provided by the tether (4), which is coupled to the cited machine (2). This rotation, in conjunction with the longitudinal movement of the entire structuredevice (1), cutting tool (3) and machine tool (2), allows for the creation of internal channels in the parts undergoing machining. These channels may have different depths, depending on the radial parameter which, in conjunction with the two aforementioned movements, are programmed by the operator at the control unit of the device.

[0075] In a particular embodiment, the rotational movement imposed by the machine tool (2) allows a maximum of 6000 rpm and a power of 33 kw. In order to allow the rotation movement to be transmitted to the cutting tool (3), in particular, its internal rod (8), is coupled to a rotation adapter (6), coupled to the rotating interface (5), which moves together with the fixing cone (7). In this particular embodiment, the cutting tool (3) comprises two cutting blades (10, 11) located in the cylinder head (9).

[0076] In order to initiate the process of machining the part that it is intended to work, the latter is placed with the cutting tool (3) by the action of longitudinal movements of the machine tool (2). Then, and with the rotational movement already initiated, the cutting tool (3) is introduced into the drill of the part to be machined, which was previously opened. In order to produce the internal channels, the controller of the device (1), after defining the necessary parametersrotational, longitudinal and radialwhich may vary depending on the specificities of each part to be machined, provokes a longitudinal movement in the rod (8) placed inside the cutting tool (3), which activates the cutting blades (10, 11) which allow the opening up of the intended channels.

[0077] In a particular embodiment, the longitudinal movement of the rod (8) can extend to a maximum of 150 mm, having been previously parameterized by the controller.

[0078] This description is clearly, in no way, limited to the embodiments presented in this document and a person with average knowledge of the field could foresee many possibilities of modifying it without departing from the general idea, as defined in the claims. The preferential embodiments described above are obviously combinable with each other. The following claims additionally define preferential embodiments.
