PROBLEM TO BE SOLVED: To provide a laser beam machine which facilitates maintenance and replacement of a cutting plate cleaning device.SOLUTION: A laser beam machine includes: a table (3) which is regulated by the orthogonal XY axis and is horizontally extended; a machining head (11) which is moved in the Y axis direction and applies a laser beam toward the table; a pair of cutting plates (8a,8b) which are provided on the table (3), have a work-piece support brush (8c) and are oppositely-separately arranged so as to form a dropping hole (9) corresponding to an irradiation position of the laser beam; a carriage (6) which has a clamper (7) for gripping a work-piece (W) and is moved in the X axis direction; and a cleaning device (21) which is freely attachable and detachable for an end part (6b) in the X axis direction of the carriage. The cleaning device includes an attachment fixture (22) which is freely attachable and detachable for an end part, a brush part (26b) and an actuator (25a) which vertically moves the brush part between a first height position and a second height position and maintains the brush part on each position. A lower end part (26c) of the brush part is separated to the upper side of the work-piece support brush on the first height position and interferes with the work-piece support brush on the second height position.SELECTED DRAWING: Figure 2 |
