CUTTING DEVICE

PROBLEM TO BE SOLVED: To provide a cutting device which allows reduction of manufacturing cost by making a program for three-dimensionally operating a machining tool simple and inexpensive. SOLUTION: This cutting device includes a supporting means 4 supporting a machining head 2 on an upper side of a table 1 and rotating a Z-axis as a rotary shaft L1. The machining tool 3 is mounted on the machining head 2, while being inclined to the Z-axis at a prescribed angle, and the machining head 2 is made movable in a rotary shaft L2 direction of the machining tool 3. The machining head 2 is moved three-dimensionally relatively to a workpiece W in such a state that a semi-spherical center C position at the distal end of the machining tool 3 is held on the rotary shaft L1 of the supporting means 4, to perform cutting.
