Iron Cam Assembly with Stepped Camshaft and Offset Cam Lobes

When bearing journal diameter and cam lobe base circle runout on a stepped camshaft are not measured from the same datum, assembled valve timing deviates from specification; runout measured from the front bearing journal must carry through to the rearmost lobe position to confirm the timing error is within tolerance. Chongqing Xinxin Zhiquan Machinery Manufacturing (Tongliang District, Chongqing) CNC-mills this iron stepped camshaft with offset cam lobes, finish-machining all bearing journals, with journal diameter, cam lobe lift profile, and step transitions controlled to your released dimensions callouts. IATF16949 certification at Xinxin Zhiquan's Chongqing facility (close to 15,000 m²) governs inspection process documentation for automotive engine, agricultural machinery, and motorcycle camshaft applications.
