Abstract:
1. A method for the manufacture of a toothed gear from a gear blank wherein the gear blank is loaded into a machine tool and rotationally driven and is machined by a hobbing cutter disposed on a rotationally driven tool shaft, and the rough-hobbed gear, once produced, is subsequently cleared of burr by means of a rotationally driven deburring tool by causing said deburring tool to chamfer front-end edges of inter-teeth grooves, wherein the number of revolutions of said deburring tool and rough-hobbed gear has a constant ratio, characterized in that the removal of burr is performed on said rough-hobbed gear invariably loaded on said machine tool in a continuous pass by using said deburring tool, which deburring tool is similar to a side milling cutter, has cutting teeth having cutting edges that are each asymmetric relative to a central plane of the deburring tool, and is fixedly disposed for rotation on the shaft of said hobbing cutter, wherein the front-end edges of the inter-teeth grooves are successively machined in the way of a gear hobbing process, and wherein said shaft is changed from the gear hobbing setting over to a burr removal setting to perform said burr removal.
