Patent ID: 8707528

Claim:
An apparatus comprising: a turning machine ( 22 ) having a workpiece spindle ( 22 . 1 ) and a counter-holder ( 23 ) arranged coaxially to a rotational axis (B 1 ) of the workpiece spindle ( 22 . 1 ) for coaxially clamping a workpiece blank (K 1 ); a tool base ( 24 ) which is displaceable relative to the workpiece blank (K 1 ) held in the turning machine ( 22 ) and comprising a multifunctional tool holder ( 25 ) mounted to rotate about an axis (B 2 ) extending substantially parallel to the rotational axis of the workpiece spindle (B 1 ), wherein the multifunctional tool holder ( 25 ) is configured for fastening at least one tool and subjecting the workpiece blank (K 1 ) to a turning process; a tool housing ( 26 ) displaceable relative to the workpiece blank (K 1 ) held in the turning machine ( 22 ), with a milling head ( 27 ) chucked in the tool housing ( 26 ), wherein the milling head ( 27 ) is mounted to rotate about a milling head axis (B 3 ) that is arranged at an angle (W) adjustable with respect to the rotational axis of the workpiece spindle ( 22 . 1 ), and the milling head ( 27 ) is equipped with a set of cutters protruding from an axial end face thereof with respect to said milling head axis (B 3 ), the tool housing ( 26 ) also being arranged to advance the milling head ( 27 ) towards the workpiece blank (K 1 ) to engage the set of cutters with the workpiece blank in order to perform toothing machining of the workpiece blank (K 1 ); and a CNC controller configured for controlling different movement processes of the tool base ( 24 ), the multifunctional tool holder ( 25 ), the tool housing ( 26 ), and the workpiece spindle ( 22 . 1 ) in order to subject the workpiece blank (K 1 ) firstly to a turning process with a tool fixed to the multifunctional tool holder ( 25 ) and then to the toothing machining with the milling head ( 27 ), such that the apparatus ( 20 ) is configured for producing a bevel gear from the workpiece blank (K 1 ).
