LASER BEAM MACHINE

To suppress rattling of a workpiece with an inexpensive configuration.SOLUTION: A laser beam machine 10 includes: a palette 50 for mounting a workpiece W; a processing head 30 for irradiating the workpiece with a laser beam, and subjecting the workpiece to laser processing; a dust collection chamber 60 which is provided so as to surround a space below the palette 50, and collects powder dust accompanying the laser processing; a dust collection duct 61 for sucking air in the dust collection chamber 60; a processing table 80 which is formed into a size smaller than the palette 50 and is arranged in a predetermined section in the palette 50; a suction table 81 provided so as to surround a space below the processing table 80; a suction duct 85 for sucking air in the suction table 81; and a switching device 70 for switching a flow of air drawn by a dust collection device between the dust collection duct 61 and the suction duct 85.SELECTED DRAWING: Figure 1 【課題】安価な構成でワークのばたつきを抑制する。【解決手段】レーザ加工機１０は、ワークＷを載置するためのパレット５０と、レーザビームを照射してレーザ加工を行う加工ヘッド３０と、パレット５０の下方の空間を囲むように設けられ、レーザ加工に伴う粉塵を集める集塵室６０と、集塵室６０内の空気を吸引する集塵ダクト６１と、パレット５０よりも小さなサイズに形成されて、パレット５０内の所定区画に配置される加工用テーブル８０と、加工用テーブル８０の下方の空間を囲むように設けられる吸引テーブル８１と、吸引テーブル８１内の空気を吸引する吸引ダクト８５と、集塵装置が引き込む空気の流れを集塵ダクト６１と吸引ダクト８５とで切り替える切替装置７０と、を備えている。【選択図】図１
