Claims

[Scope of utility model registration request]

In a laser processing machine, etc., in which a workpiece is placed on a crest provided on a movable table and the workpiece is moved together with the movable table relative to a processing nozzle for cutting, the movable table has a plurality of suction ports and opening/closing valves. Dust collection ducts are arranged in parallel at required intervals in the movement direction of the movable table, with the length direction substantially perpendicular to the movement direction of the movable table, and the on-off valve is used to collect dust that has entered a predetermined range of the processing nozzle. A dust collection device for a laser processing machine, etc., characterized in that it is equipped with an opening/closing control means that opens an on-off valve of a duct and closes an on-off valve of a dust collection duct that goes out of a predetermined range of a processing nozzle.
