  • Method of manufacturing a camshaft
    Patent number: 6289764
    Abstract: A method of manufacturing a camshaft comprises the first step of casting a blank defining a central shaft, concentric journal bearings and eccentric cam lobes, the cam nose region between the journal bearing at the driven end of the camshaft and the adjacent cam lobe being cast in the same non-circular shape as the cam lobe but with smaller dimensions. The cam nose and the cam surface of the first cam lobe are then ground. Preferably, the cam lobe surface and the cam nose are ground at the same time as one another by means of a shaped grinding wheel having a cylindrical portion for grinding the cam surface and a narrower contoured portion of larger diameter at one end for grinding the cam nose.
