PURPOSE:To improve the efficiency of the cutting work by applying the seesaw motion to a band saw supported by a band saw support frame and freely adjusting the amplitude of the frame via the position change of a pair of detectors (e.g., switches). CONSTITUTION:A pair of push-pull drive device 10a, 10b are speed-controllably providedon a support frame 9 supporting a band saw (not shown in the figure), and drive directions are reversed to each other, and the seesaw motion is applied to the frame 9. The seesaw motion is freely adjusted via the position change of detection switches not shown in the figure, and the cutting stroke length of the band saw is adjusted, thereby the cutting work can be efficiently performed by adjusting the position of the detection switches in advance. |
