fi ne grinding processes, surfaces up to approximately Ra = 0.2 µm can be realized. To achieve fi ner surfaces, additional grinding wheels with an elastic bonding system can also be installed on the tool spindle of the grinding machine. Con-ventional gear grinding is then followed by polish-grinding with very little stock removal.

Fine Grinding (flat parts – single or double-side) is the abrasive machining process for removing material using a bonded Superabrasive wheel at low speed with a liquid to keep the part cool. The fixed grain of a geometrically indefinable cutting shape acts like a plow (fig. 3) and material is removed by micro-grooving /-cutting (fig. 4). ...
