Abstract
To provide a loading cam device which is capable of ensuring a necessary accuracy, improving the efficiency of the formation of a cam face, and reducing the manufacturing cost. A cam plate is fixedly secured to a chuck rotationally driven by a main shaft. A cutter is axially placed on one surface of the cam plate. A holder holding the cutter is axially displaced in synchronism with the rotation of the chuck to make an irregularity conforming with the cross-sectional configuration of the cam face. In addition, a header is displaced in the diametrical directions of the chuck to make an irregularity throughout.
