PROBLEM TO BE SOLVED: To prevent the dispersion of fume, dust, scattered light and reflected light and to improve the dust collecting and the fume collecting efficiency by closing a working table except a work at the time of executing the heat cutting to the work. SOLUTION: In a heat cutting machine provided with a working head for executing heat cutting by irradiating the work with heat cutting beam, plural work supporting member 27 are arranged at the suitable interval in one direction on the working table 5 shiftably arranged at the lower part of the working head. A dispersion preventing cover 29 for closing the upper part of the working table 5 except the work WB is arranged in the condition of supporting the work WB on the work supporting member 27. Further, this dispersion preventing cover 29 is constituted of a first slide cover 39 slid in one direction on a shifting cover 33 shiftably in the direction by providing a groove for shifting pitch by pitch in the work supporting member 27 and second covers 45A-45D slid in the other direction on the working table 5. |
