PURPOSE:To previously store cutting conditions in an incorporating computer and to automatically control cutting speed corresponding to an instruction of the computer. CONSTITUTION:A normal-descent band sawing machine 5 is inclined downward to the left, which is peculiar to a saw blade 9, and circulates as it is. Fluid pressure is supplied 15 to a liquid pressure cylinder 13 to raise a housing 17, which is lowered by a lowering device 1. A computer 23 includes a memory 27 for previously storing cutting conditions, a comparator 29, and a command device 31. The command device 31 commands a motor 33 to rotate at a desired speed of rotation. A piston rod 35 is provided with a rack 37, which is controlled to descend and ascend by a pulse ocsillator 39. |
