Abstract:
The purpose of the present invention is to increase the collection rate of grinding liquid when cutting a workpiece having a plate thickness changing in the longitudinal direction (vertical direction) and/or the width direction (horizontal direction), and to improve the work environment of a worker. An abrasive water jet machining device is provided with: an abrasive nozzle assembly (11) that jets ultra high pressure water mixed with an abrasive when a workpiece (W) is cut in a desired shape; a catcher cup (12) that collects the ultra high pressure water injected from the abrasive nozzle assembly (11); and a distance adjusting mechanism (13) that adjusts the distance between the abrasive nozzle assembly (11) and the catcher cup (12) so that the distance between the catcher cup (12) and the workpiece (W) is kept constant.
