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.
Claims7
A method for the precision working of the tooth flanks of particularly hardened gears (workpiece W) with a gearlike tool, the flanks of which tool have an abrasive surface, namely, a surface which does not have uniformly directed cutting edges, with the tool rotating with the workpiece in a reciprocal mesh, comprising the steps of:
- selecting a twin tool having two axially spaced tools with the same dimensions at least with respect to their number of teeth, the module and the pitch angle, which tools are used one after the other without necessitating the workpiece to be rechucked, such that:
- a) with the first tool in a two-flank contact with the workpiece remaining burrs and other irregularities are removed from the tooth flanks of the workpiece, and thereafter
- b) with the second tool also in a two-flank contact with the workpiece the actual precision working of the tooth flanks of the workpiece is done.
