ABSTRACT:
A method for the manufacture of a toothed gear from a gear blank wherein the gear blank loaded into a machine tool and rotationally driven 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 it to chamfer the front-end edges of the inter-teeth grooves, wherein the number of revolutions of said deburring tool and rough-machined gear has a constant ratio, wherein the removal of burr is performed on said rough-machined gear invariably loaded on said machine tool in a continuous pass by using a deburring tool which is similar to a side milling cutter, has cutting teeth, 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.
