Abstract: A cutting machine includes a cutting machine main body configured to cut a material transported along a longitudinal direction of a material into a plurality of cut materials, a material supply device and a product carrying-out device configured to carry the material into the cutting machine main body and to sort and carry out each of the plurality of cut materials into a product yard for accommodating a product or a residual material yard for accommodating a residual material of the material, respectively, and an NC device configured to control the cutting machine main body, the material supply device, and the product carrying-out device. The NC device is provided with a first operation mode for causing all of the plurality of cut materials to be carried out to the product yard 45.

Abstract: A band saw is includes a driving wheel and a driven wheel rotatably provided at a saw housing; an endless saw band made to run around the driving wheel and the driven wheel; and a plurality of saw band guiding devices for directing and guiding cutting edges of the saw band toward a direction of a workpiece to be cut. The saw band guiding devices are constructed to be movable in directions where one of the guiding devices gets closer to and away from another of the guiding devices, wherein each of the saw band guiding devices includes vibrating means for vibrating the saw band in a cutting direction relative to the workpiece. A pressure member holder including a plurality of pressure rollers or a pressure member for pressing a back surface of the saw band is provided in each of the saw band guiding devices.
