摘要

Cutting a steel component, stainless steel, brass, copper, titanium, aluminum and aluminum alloy or plastic, comprises: (a) implementing a laser generator to generate a laser beam; (b) conveying laser beam between the laser generator and laser head; (c) focusing laser beam on the component; (d) compressing air at 7-40 bars; (e) treating the compressed air to eliminate a part of the impurities, steam and contained oil vapor; (f) recovering the treated air; and (g) introducing recovered air at a rate of 5-300 m 3/h and at a pressure of 7-40 bars, in the laser head. Cutting a steel component, stainless steel, brass, copper, titanium, aluminum and aluminum alloy or plastic by laser beam, comprises: (a) implementing a laser generator for generating a laser beam; (b) conveying the laser beam between the laser generator and laser head comprising a focusing lens; (c) focusing the laser beam on the component to be cut by the focusing lens; (d) compressing air at a pressure of 7-40 bars; (e) treating the compressed air to eliminate at least a part of the impurities, steam and contained oil vapor; (f) recovering the treated air having a dew point of 0[deg] C to -80[deg] C, a maximum density of aerosol particles of 0.01-5 mg/m 3, a maximum diameter of particles being 0.01-5 mu m, and a maximum content of oil vapor being 0.001-0.1 mg/m 3; and (g) introducing recovered air at a rate of 5-300 m 3/h and at a pressure of 7-40 bars, in the laser head.
