Specifically, when cutting the work piece man-hour, earlier fix a position the centre gripping through the mechanical chuck to the unprocessed position of work piece, confirm behind the cutting process (including horizontal cutting, vertical cutting or circumference rotary cutting), adjust the preliminary position of laser cutting device, utilize preliminary locating component to carry out preliminary location to the cutting point of the preliminary contact work piece surface of laser ray, wherein, in the coincidence department of the illumination point of light source emission group one and light source emission group two, be the preliminary cutting setpoint of this laser cutting device promptly, carry out preliminary cutting work to the work piece by laser cutting device again, and, in cutting process, the inside and outside air current exchange is realized to the air current drainage system, in time get rid of the flue gas that the cutting produced.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution of the present invention and the inventive concept within the technical scope of the present invention, and the technical solution and the inventive concept thereof should be covered by the scope of the present invention.
