A manufacturing cell for the treatment of grinding of gear wheel flanks, in particular by bevel pinions, and suggested for the wheel set testing, which includes a grinding machine (1), an unreeling test equipment (2), a laser inscription unit (3) with a time band (5) and a robot-supported load system (4), which are concatenated with one another and controllable that the process of pinion loops/wheel set examining/marking and the correction of the grinding machine attitude as a function of the results of the unreeling examination is feasible.
