PURPOSE: A vehicle camshaft manufacturing method is provided to reduce manufacturing costs by manufacturing a cam lobe of a forging material and to obtain a camshaft with improved durability through high-frequency heat treatment. CONSTITUTION: A vehicle camshaft manufacturing method includes the following steps of: forming a cam lobe by using a forging material(S100,S110); temporarily assembling the cam lobe with a shaft through spot-welding(S120); bonding the cam lobe with the shaft by brazing(S140); and hardening the cam lobe assembled with the shaft through high-frequency heat treatment(S150). [Reference numerals] (S100) Forge a cam lobe; (S110) Process an inner diameter of the cam lobe; (S120) Spot-weld the cam lobe and a shaft; (S130) Spread a metal insert (Using an SUS-based metal insert); (S140) Braze; (S150) High-frequency heat treatment; (S160) Bending-correction; (S170) Friction-weld an end piece; (S180) Grind |
