Improvement And Optimization Of Process For Camshaft Of Motorcycle

This study is according enormous defect analysis of quality, technology analysis and craft test, analyzing and discussing about the reason which caused varies defect in the production of motor's camshafts, found out the factor which affected the ultima performance and life-span, and bring forward the methods for optimizing and advancing the technology.Result show, under present processing, the factors which affecting the ultima performance and life-span are the surface hardness of cam and the quantity of remaining eutectic carbide in surface microstructure .the key to control the quantity of remaining eutectic carbide after high-temperature graphitization annealing is controlling the silicon quantity in the chemical indegrient of blank .it can efficiently to avoid the lack of hardness, overheat and oversinter after camshaft's high-frequency quenching ,with the employing of quench and high-temperature temper instead camshaft's low-temperature annealing.
