Method for the manufacture of a gear component, and gear grinding machine

A method for the manufacture of a gear component, such as a gear wheel, comprising:

• in a soft machining process, introducing a preliminary toothing (3) having a machining allowance (7) that is fixed relative to a final toothing (4) into a blank such that a semi-finished part (2) is produced;
• and
• in a fine machining process, removing the machining allowance (7) and producing the final toothing (4) of the gear component,
• wherein the machining allowance (7) is removed in a single-stage hobbing method by a grinding tool (1), and the grinding tool (1) removes the machining allowance completely in a single stroke movement (H),
• wherein, in the soft machining process, the machining allowance (7) is produced with a value less than fifty micrometers,
• wherein the grinding tool (1) comprises abrasive grains that remove the machining allowance (7) and produce the final toothing (4) of the gear component during the single stroke movement (H),
• wherein the grinding tool (1) removes the machining allowance (7) simultaneously from both flanks of each tooth of the preliminary toothing (3) during the single stroke movement (H), and
• wherein the semi-finished part (2) is rotated about a workpiece axis (A1) during the fine machining process, and the single stroke movement (H) is substantially parallel to the workpiece axis (A1).
