A method for manufacturing a hollow camshaft is provided, and more particularly, a method for manufacturing a combined hollow camshaft by an axial-compression upsetting-deformation technique. The present method solves a problem that the current camshaft manufactured in an internal high-pressure expansion manner in the prior art has the insufficient locking force to cause the loosening of a cam. The method is as follows: a camshaft is formed by combining two independent units, namely a cam and a shaft tube. Non-circular countersinks are distributed on two sides of the cam. Thrust steps are formed on the shaft tube correspondingly. The cam is placed between the two thrust steps of the shaft tube. The locking force is applied to the cam by utilizing the thrust steps on the two sides of the cam based on thermal expansion and contraction. Simultaneously, the thrust steps lock the cam with the countersinks.
