ABSTRACT:
Apparatus for grinding a helical cutting surface on a flat cutting blade. Prior art grinders are complex, difficult to operate and expensive to use. The present grinding machine comprises a stationary support (74), a grinding arbor (76), an adjustable cam plate (78), a grinder carriage assembly (80), a grinder assembly (82), cam follower (112), mounted on the grinder carriage assembly (80), and a grinding stone (128) mounted on the grinder carriage assembly (80). When the carriage and the grinding stone are reciprocated along the axis of rotation of the grinding arbor the cam follower (112) contacts the lower surface of the cam plate (78) whereby the grinding arbor is oscillated about its axis of rotation and a helical cutting surface is ground into the blade (34).
