Method and device for machining a toothing on a sintered part

A method of machining a toothing on an outer circumference or an inner circumference of a work piece made of pressed and sintered powder metal with the work piece secured on a holder, the machining occurring via a rolling process on the toothing using two rotatable section rolling wheels, which have a section toothing engaging in the toothing of the piece,

• wherein the two section rolling wheels are arranged in a rotating manner in a common support frame designed in one piece,
• wherein the holder for the work piece is mounted on a spindle and is driven by an actuator device via the spindle such that a driving torque is transmitted to the work piece by the actuator device for the rolling process,
• wherein the two section rolling wheels are each freely rotatable about a respective section rolling wheel axle supported directly in the support frame so that once the two section rolling wheels are engaged in the toothing of the work piece, the section rolling wheels roll on the toothing,
• wherein one section rolling wheel axle is arranged movably on the support frame at least approximately tangentially with regard to the second rolling wheel axle, and
• wherein the moveable section rolling wheel axle is disposed in a guided slot arranged in the support frame and is directly guided in the guided slot such that the moveable section rolling wheel axle has an additional mobility with regard to the support frame, the additional mobility supporting the mutual engaging of the section toothing in the toothing, said moveable section rolling wheel axle being guided about an entire length of the guided slot.
