Assembled camshafts are attracted attention as competitive products and technologies for camshaft manufacture because of its unique, composite design and special features compared to conventional camshafts, which are manufactured by producing the individual elements in separate forming stages and fastening cam lobes and axle journals on a hollow axis. In the paper, the conventional camshafts as well as production techniques were analyzed, the principles and advantages of the assembled camshafts were discussed. Some key techniques such as joint methods between cam lobes and shaft, precision forming of the lobes, assembly and assembly equipment were presented. The developments and applications of the technology were introduced.
