Rotor and method of manufacturing rotor with equalized surface areas for grinding
A rotor for a variable valve timing engine is disclosed in which the opposing planar surface(s) of the rotor have one or more recesses formed therein in order to balance, equilibrate, or equalize the planar surface areas on the opposing surfaces. Among other things, this can improve the accuracy and efficiency with which the rotor is ground during a related method of manufacturing the rotor.
