  • Method for the manufacture of a gear component, and gear grinding machine
    Patent number: 11278976
    Abstract: A method for the manufacture of a gear component includes, in a soft machining process, introducing a preliminary toothing 3 with 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. The method also includes, in a fine machining process, removing the machining allowance 7 and producing the final toothing 4 of the toothed component. The machining allowance 7 is removed in a single-stage hobbing method by a grinding tool 1, wherein the grinding tool 1 removes the machining allowance completely in a single stroke movement H.
