ABSTRACT:
A methode serves for producing bores in wheels of motor vehichles, in particular for producing mounting bores (14) in a wheel disk (12) or valve bores in a rim of the wheels. The bore has a larger diameter (D.sub.1, D.sub.3) in the area of the surfaces (135, 136) of the wheel disk than in the area between these surfaces.
In order to enable a countersunk portion to be produced in the area of the bore also in the surface opposite the machining surface, with the wheel in a signle mounting position, a tool (160) is employed whose bottom face exhibits a hook-like configuration (162, 163, 164, 165) and which can be passed through the bore in vertical direction (170), in axially displaced relation. Thereafter, the tool (160) is returned to a position in which it is aligned with the axis (15) of the bore, then rotated and retracted. whereby a countersunk portion (144) of larger diameter is produced. Finally, the tool can be removed from the bore by carrying out the described steps in the reverse order.
