Abstract
A cutting device capable of obtaining high speeds, approximately three times faster than known cutting devices by using a structure employing an internal positive cam. A rotary slider rotates upon rotation of a spline shaft via a gearbox, and the operation is such that a track of a wedge-shaped blade tip of a male cutter lies along a workpiece via cam followers slidably rotating over a sliding surface of an internal positive cam, cutting the workpiece.
