[0026] FIG. 3 shows a perspective view of a section of a cutting tool according to the invention according to a second embodiment, and

[0027] FIG. 4 shows a plan view of the reinforcing part of FIG. 3.

DETAILED DESCRIPTION

[0028] FIG. 1 shows a cutting tool 10 with a main body 12 produced from metal.

[0029] This is a combination tool for combined face and circumference processing, specially designed for processing crankshafts of internal combustion engines.

[0030] Likewise, the cutting tool 10 can however also be a milling tool, a turning tool, a drilling tool, a thread cutting tool, a broaching tool, a turn broaching tool, a reaming tool, a deburring tool and/or a multifunctional tool.

[0031] The main body 12 of the cutting tool 10 is reinforced with a reinforcing material 14 that is a fiber material in the described embodiment (see FIG. 2).

[0032] In this case, the main body 12 has the shape of an annular disk to a face of which the reinforcing material 14 is attached. The other face is not visible. Of course, the reinforcing material 14 can also be attached thereto.

[0033] The reinforcing material 14 is applied to the outside of the main body 12 and attached thereto.

[0034] In the portrayed exemplary embodiment, the reinforcing material 14 runs in a closed ring around a rotational axis A of the cutting tool 10.

[0035] The main body 12 is produced from a steel material, and the reinforcing material 14 is a carbon fiber material.

[0036] The reinforcing material 14 can alternatively be a glass fiber material, a natural fiber material, a ceramic fiber material and/or an aramid fiber material. Likewise, the main body 12 can be produced from any other metal.

[0037] The main body 12 comprises first functional surfaces 16a that are designed as a seat for a cutting insert 18, in this case indexable insert seats.

[0038] Moreover, the main body 12 comprises second functional surfaces 16b that are designed as contact surfaces in the broadest sense for a machine tool (not shown).

[0039] The functional surfaces 16a, 16b do not comprise any reinforcing material 14.

[0040] In the portrayed cutting tool 10, two cutting inserts 18, which are indexable inserts in the portrayed embodiment, are provided by way of example.

[0041] The cutting inserts 18 are attached to cutting insert seats 20 arranged on the main body 12. However, for reasons of clarity, not all cutting insert seats 20 are provided with cutting inserts 18.

[0042] In the portrayed embodiment, the cutting tool 10 weighs less than 15 kg and has a rigidity that substantially corresponds to a rigidity of a functionally equivalent, unreinforced tool that has an identical outer geometry and is produced entirely from steel.

[0043] FIGS. 3 and 4 show a second embodiment of the cutting tool 10 in which the reinforcing material 14 is an aluminum material. In the following, only the differences from the first embodiment will be addressed.

[0044] The reinforcing material 14 in this case has the shape of an annular disk and is designed as a reinforcing part 22 separate from the main body 12.

[0045] This reinforcing part is connected by screws 24 to the main body 12.

[0046] In contrast to the first embodiment, the functional surfaces 16b by means of which the cutting tool 10 is connected to a machine tool 26, only a section of which is shown, are now arranged on the reinforcing part 22.

[0047] In this context, a rotary driver 28 can also be seen, by means of which the cutting tool 10 is rotationally driven by the machine tool.
