Abstract
A method is described for producing a gear wheel from a powdered metal blank () compressed and sintered having a machining allowance in the gearing area, the powdered metal blank () being compacted by the machining allowance with a plastic deformation by rolling of a compression tool () forming a counter gearing engaging in the gearing of the powdered metal blank (). To provide advantageous compaction conditions, it is suggested that the powdered metal blank () be compacted simultaneously around the entire circumference by rolling of profile rolls () forming the compression tool () axially to the powdered metal blank ().
