ABSTRACT:
An operating method improves the running behavior of gearwheels negatively noticed upon gearwheel testing and is performed by a burnishing device. The gearwheels that were rejected from the production process may be optimized rapidly and in a targeted way so that they may be returned back into the production process. The tooth flanks of a gearwheel to be machined are, in a first method step, mechanically freed of particles adhering to the surfaces of the tooth flanks or slight protrusions protruding therefrom using a first gearwheel machining tool having a machining wheel coated with an abrasive agent. Subsequently, in a second method step in a second gearwheel machining tool known as a burnishing machine, the gearwheel is chucked between gearwheel-shaped rolling tools, the so-called burnishing wheels, and rolled without material abrasion.
