摘要： First and second rotary units (110, 120) comprises a pair of rotators (111, 121) disposed oppositely, and hitting bodies (130, 140) fixed rotatably to shafts (113, 123) spanning between the rotators. The hitting bodies (130, 140) have a specified fitting gap with the shafts and are fixed such that a part of outer circumference thereof can be located on the outside of the outer circumference of the rotator. When the first and second rotary units rotate at a high speed, the hitting bodies thereof collide sequentially against an object to be machined to cut the object. Cutting depth by the hitting bodies of the second rotary unit is deeper than the cutting depth by the hitting bodies of the first rotary unit and the hitting bodies of at least one rotary unit collide against the object at a speed not lower than the critical hitting speed. An object comprising a single member or a composite members can be cut using a single cutting tool and the lifetime and reliability of a cutting apparatus are enhanced.
