Kind Code:
B2
Abstract:
To provide a bandsaw device capable of detecting slips of a bandsaw blade with high accuracy.SOLUTION: A bandsaw device comprising a driving pulley to which driving force from a motor is transmitted via a driving force transmission device, a driven pulley, and an annular bandsaw blade wound between the driving pulley and the driven pulley is configured to be provided with: a rotational speed sensor for the driving pulley to detect a rotational speed of the driving pulley; a speed sensor of the bandsaw blade to detect a speed of the bandsaw blade; and a slip amount calculation section calculating the slip amount of the bandsaw blade through comparing an estimated speed of a first bandsaw blade calculated based on a detected result by the rotational speed sensor for the driving pulley with an actual speed of the bandsaw blade detected with the speed sensor of the bandsaw blade.SELECTED DRAWING: Figure 1
