[0032] FIG. 1 an invented device 21 to process in perspective view. The device 21 is invented to process a rim 1 for a vehicle, in particular a passenger car. A rim 1 is delivered to a support device 2 in the centre of the device 21 using a transport system 19 with example transport rollers 20. The device 21 comprises as an example the support device 2 of the rim, a centring device 3 and a drilling device that is out of view. A device to press the rim down 17 what is positioned in the rim has a disc-shaped element 18 with cut-outs 24 for the centring device 3. The support device 2 of the rim has a cone-shaped element that can be inserted into the inner part of the rims shown in FIG. 4 as an example. The rim 1 is positioned in one direction 7 facing downward on the support device 2 and sideward from the two centring devices 3 that are positioned on opposite sides, as shown in FIG. 2.

[0033] FIG. 2 is an invented device to process 21 in partial view. The transport device 19 with transport rollers 20 moves two rims 1 one after the other to the support device 2 and are held in a centred position by the device 3. The transport system 19 can also be used as a centring device to position the rim 1 in a centred position. As soon as a rim has been processed it is grabbed and transported onward on the transport system using the centring device after this has grabbed a new rim.

[0034] FIG. 3 is an invented device to process 21 in perspective view. A disc-shaped element 18 of a device to press the rim downward 17 with cut-outs 24 lowers itself vertically onto the rim 1. The rim is lying on the support device and delivered by the transport rollers 20. A cone-shaped element 5 is inserted from below. Later the drilling chips can be collected in a drilling chip collector 25.

[0035] FIG. 4 is an invented device to process 21 in sectional view.

[0036] The rim 2 is positioned concentrically to the processing axis 9 in a central wheel hub shaft 8. The rim is held in place using a press-down device 17.

[0037] In a wheel hub area 10 a hole can be drilled through the cone-shaped element 5 of the support device 2 which can be inserted into the wheel hub area 10 from one direction 11 of the inner surface of the rim 2 with the drilling device 4.

[0038] FIG. 5 is an invented device to process 21 in sectional view. The drilling device 4 is drilled through to the wheel hub area 10.

[0039] FIG. 6 a section of an invented device 2 to process in sectional view. The cone-shaped element 5 must be positioned, at least while drilling, so that it can be fed through the cone-shaped element 5 into the wheel hub area 10 with one drilling action from one direction 11 of the inner surface 6 of the rim 1 with the drilling device 4. The cone-shaped element 5 prevents drilling chips 13 from falling onto or into the rim and retains them in an outer area 12. The drilling chips 13 fall into the inner area 14 of the rim 1. The cone-shaped element only has a passage 15 to the wheel hub area 10 that is adapted to fit the drill diameter 16. The rim 2 is held in place on the cone-shaped element 5 mainly using the press-down device 17 of the rim. The part 22 remaining after drilling can be removed in the stamping process that occurs afterwards.

[0040] FIG. 7 shows an invented device 21 to process a rim 1 in sectional view, where the material detail processing device 26 in particular machining, in this case a milling process in combination with a circular motion and/or a helix-shaped process motion of a milling device.

[0041] The material detail processing device 26 is positioned in a central area of the rim. The device 21 to process the rim 1 comprises a material detail processing device 26 in particular for machining where the rim 2 is held with the inner surface 6 in the direction 7 facing downward and the rim 2 is held mainly concentrically on a central wheel hub shaft 8 to a central axis 30 of a circular movement and/or helix-shaped movement whereby in a wheel hub area 10 from one direction 11 of the inner surface 6 of the rim 1 with the material detail processing device 26, in particular a milling insert 28, can be inserted through the support device into the rim hub area 10.

[0042] FIG. 8 shown an invented device 21 to process in sectional view with a material detail processing device 26, with a milling insert 28 in a sideward circular position whereby the milling insert can be used with approx. 12,000 revolutions.

[0043] FIG. 9 shown an invented device 21 to process in sectional view with a material detail processing device 26, with a milling insert 28 in a sideward position on a circular motion line 31. The advantage of the device here is that it can be used with different diameters 32 of the material detail processing in the rim. The smallest possible diameter is selected as the milling device in order to produce larger inner rim holes using circular, perhaps CNC controlled milling devices. A controlled cross table, a circular table or another suitable system effects a motion that is horizontal to the drilling spindle in the x-axis and y-axis. The z-axis determined the milling depth/drilling depth in the rim. The same effect of the circular milling process could also be produced by moving the rim accordingly.
