Abstract
Cam and cam follower apparatus in which the cam follower comprises a body having a cavity at one end and a diamond material filling the cavity. The cam member is substantially cylindrical and has a longitudinal axis about which the cam member is curved. The cam follower has a diamond material working surface which is curved in planes parallel to the longitudinal axis of the cam and is maintained in following engagement with the cam. As a result, the cam and follower have intersecting arcuate surfaces providing for substantially point contact between the surfaces, with the point being located on the diamond material. This arrangement provides for improved efficiency in the operation of the cam and the cam follower because it materially reduces wear of the follower. Thus, increased accuracy in the shape and size of the products being formed can be maintained. The hardness of the diamond filling material insures this improved efficiency.
