The invention relates to a method for producing a sintered part having a highly precise molded part height, the sintered part being produced from a first sintered joining part that has a first joining surface and a second sintered joining part that has at least a second joining surface. The method comprises at least the following steps: joining the first sintered joining part and the second sintered joining part, the first joining surface being oriented such that it faces the second joining surface; pressing the first sintered joining part and the second sintered joining part against each other under axial compression pressure exerted by a pressing tool, the highly precise molded part height being brought about by pressing the parts against each other; removing the sintered part from the pressing tool as a sintered part having a highly precise molded part height. The invention also relates to a parts set of sintered joining parts.

The invention relates to a method for producing a sintered part with a high radial precision. The sintered part is made of at least one first joining part to be sintered and a second joining part to be sintered, and the method has at least the following steps: joining the first joining part with the second joining part, and bringing about the high radial precision, having a step of deforming at least one radial deformation element which is preferably positioned so as to adjoin a joint contact zone, wherein the deformation of the radial deformation element is caused at least by means of a calibration tool and is carried out at least substantially as a plastic deformation of the radial deformation element. The invention further relates to a set of parts for joining the joining parts to be sintered into a sintered part with a high radial precision.

The invention relates to a rotor for a camshaft adjuster for rotation about a rotation axis. The rotor has an inner sheath and an outer sheath and at least one control vane, pointing at least substantially radially away from the rotation axis, having a first control vane side and a second control vane side. The rotor furthermore has a first liquid channel system and a second liquid channel system, wherein the first liquid channel system opens in a first liquid channel opening and the second liquid channel system opens in a second liquid channel opening. The rotor comprises: a first sintered joining part, a second sintered joining part which is joined to the first sintered joining part and an insert part which is inserted in an intermediate chamber which is formed by at least one of a first recess of the first sintered joining part and a second recess of the second sintered joining part. The invention further relates to a parts set and to a method for producing a joined component.
