PROBLEM TO BE SOLVED: To enable very efficient cutting of a steel frame like an H-shaped steel using a small cutting machine, and to demolish efficiently a heavy oil tank or a gas tank. SOLUTION: The cutting machine comprises an outer casing 1 of a crusher, double-edge mountable movable bodies 2, 2 base parts of which are respectively journalled to the outer casing 1 at a predetermined interval by shafts 3 in a manner of swinging while facing each other for a holding purpose, and hydraulic cylinders 4, 4 which are structured so that the double-edge mountable movable bodies 2, 2 can swing independently. The edge fitting movable body 2 comprises a beak-like part 21 on the front end side and a straight part 22 on the base side. The beak-like part 21 comprises a front end inclined part 21a and a gently inclined part 21b, which form two-phased inclination. A front end cutting edge 6 is fixed to the gently inclined part 21b and a cutting edge 5 is fixed to the straight part 22 of the edge mountable movable body 2 in a freely cuttable manner.
