Device And Method For Roughing And Fine-Machining Of Gears

Abstract

A method for cutting teeth into working gears using a tool, the tool main part of which has a plurality of cutting teeth which are arranged about a rotational axis and which protrude radially from the tool main part, the cutting teeth forming an end face, two tooth flanks which point away from each other, and cutting edges. The cutting edges are formed from the tooth flank edges adjoining the end face. In a first method step, tooth gaps which form tooth flanks are produced in the working gear by means of the cutting edges using a machining process in a first position of the tool relative to the working gear, and in a second method step, the working gear tooth flanks produced by the cutting edges are fine-machined by an abrasive tool surface.

         8 . A tool for cutting the teeth of working gears with a main part, which has a multiplicity of cutting teeth arranged about an axis of rotation and protruding radially from the main part of the tool, which cutting teeth have an end face, two tooth flanks facing away from each other, and cutting edges on the edges of the tooth flanks adjacent to the end face for the generation by machining of tooth gaps forming tooth flanks on the working gear, the tooth flanks of the tool are abrasively formed for the fine-machining of the tooth flanks of the working gear generated by the cutting edges 
     
     
         9 . The tool in accordance with  claim 8 , wherein, the tooth flanks of the tool are abrasively coated, in particular have a hard material coating. 
     
     
         10 . The tool in accordance with  claim 8 , wherein, the tooth flanks of the tool have hard material particles, in particular boron nitride, aluminium oxide, or diamonds, embedded in a metal layer, in particular a nickel layer. 
     
     
         11 . The tool in accordance with  claim 8 , wherein, the direction of extent of the cutting teeth runs at an angle to the axis of rotation. 
     
     
         12 . The tool in accordance with  claim 8 , wherein, a vertex line of the cutting teeth runs on a truncated conical surface, or a cylindrical surface, about the axis of rotation.
