Abstract

A method for the precision working of the tooth flanks of particularly hardened gears (workpiece W) with a gearlike tool, the tooth flanks of which tool have an abrasive surface and which rotates in mesh with the workpiece (W). In order to avoid damage to the tool caused by remaining burrs or the like in the tooth system of the workpiece (W), a twin tool with axially spaced similar tools is utilized, individual ones of the similar tools are used one after the other. The first tool removes thereby first the remaining burrs and the like and the second tool performs thereafter the actual precision working.
