Summary: | To provide a bandsaw capable of efficiently and automatically adjusting, a drive speed, without experienced techniques.SOLUTION: A bandsaw 10 comprises: an endless saw blade 24; a pair of wheels 26 to which the saw blade is wound; cutting means 20 having a rotation motor 28 which is connected to one wheel and is rotated; and feeding means 30 having a feeding motor 32 which moves the cutting means in a cutting direction. The bandsaw further comprises: a vibration measurement sensor 40 for detecting vibration which is generated in the cutting; a saw blade vertical position measurement sensor 50 for detecting a height position of a saw blade; a saw blade horizontal position measurement sensor 51 for detecting a horizontal position of the saw blade; a determination part 60 for comparing a measured value with a vibration set value of the vibration measurement sensor, a measured value with a saw blade height change set value of the saw blade vertical position measurement sensor, and a measured value with a saw blade position set value of the saw blade horizontal position measurement sensor; and a control part 70 for, on the basis of determination by the determination part, controlling at least one of a rotation speed of the rotation motor and rotation speed of the feeding motor.SELECTED DRAWING: Figure 1
