A cutting machine is provided to cut a plate-shaped metal material to become a desired shape by adjusting an angle of a driving frame and minimize damage of a rack gear. A cutting machine(10) comprises a diagonal correction supporting stand(20), a driving frame(14), correction screws(23a,23b), a guide rail, and a cutting torch(16). The driving frame is installed on the diagonal correction supporting stand to slide. The correction screws are used for adjusting an angle of the driving frame. The elevating unit raises or drops the cutting torch. The cutting machine cuts the metal material by adjusting the angle of the driving frame even though the metal material is not placed on a predetermined place.
