PURPOSE:To provide a laser beam machine which has been improved so that a dross can be prevented from sticking on a machined surface and an un- machined surface. CONSTITUTION:The laser beam machine is provided with a subject to be machined supporting means 2 and a laser beam machining head supporting means in order to relatively move a laser beam machining head 7 irradiating a surface to be machined 1a with a laser beam, a center gas blowing means 15 in order to make a gas in the direction parallel with the optical axis of the laser beam blow on a machining point, and a side gas blowing means 16 in order to make a gas in the direction being almost along the surface to be machined on the machining point blow. Then, the configuration is made so that a nozzle of the side gas blowing means is faced toward the un-machined portion of the surface to be machined, and together a brush means 17 brushing the surface to be machined at just before the machining point in a relative movement direction of the laser beam machining head and the surface to be machined is provided. Therefore, the quality is improved. |
