Abstract

A truing tool for truing an essentially cylindrical grinding worm that is arranged on the tool spindle of a machine suitable for the continuous generation grinding in the tangential- and diagonal process. The truing tool comprises an essentially cylindrical gear wheel ( 6 ) having an abrasive coating on the surface that is active during truing to profile the flanks of the grinding worm ( 3 ) and an essentially cylindrical roll ( 7 ) having an abrasive coating on its circumferential surface to adapt the diameter of the addendum circle of the grinding worm. The gear wheel ( 6 ) and the roll ( 7 ) can be connected axially and torsion-resistantly to the work piece spindle ( 1 ) of the machine.

Claims (6)

1. Truing tool for truing an essentially cylindrical grinding worm that is arranged on a tool spindle of a machine for continuous generation grinding in the tangential- and diagonal process, said truing tool comprising:

an essentially cylindrical gear wheel having an abrasive coating on the surface that is active during truing to profile the flanks of the grinding worm;

an essentially cylindrical roll having an abrasive coating on its circumferential surface to adapt the diameter of the addendum circle of the grinding worm;

the gear wheel and the roll being axial-resistantly and torsion-resistantly connected to a workpiece spindle of the machine.

2. The truing tool of claim 1 wherein the gear wheel and the roll are torsion-resistantly connected to one another and are connectable axial-resistantly and torsion-resistantly with the work piece spindle as a tool unit.

3. The truing tool of claim 1 wherein the gear wheel and the roll are a one piece unit.
