Abstract
An apparatus allows for chamfering and deburring the end edges of a toothed production gear in a single operation and with one and the same tool. The tool includes two pressure wheels. Provided on each pressure wheel, axially side by side, are a ring of guide teeth and a ring of deburring teeth projecting circumferentially beyond the ring of the guide teeth. The rings have a filleted transition between them and together form chamfering teeth by means of which the end edges of the production wheels are pressed radially and axially against the production gear by means of adjusting drives.
