| Abstract: | Laser processing equipment for metal tube-cutting is introduced. the cutting track is formed by the laser head moving along axis combined with the workpiece turning droven by an electric chuck circumvolve, thus the subsection cutting for the workpiece with different radius could be easily realized without changing the chuck. Low oxygen pressure cutting by air cooling can reduce the consumed oxygen by 2/3 oxygen compared with traditional ones. Its maximum single cutting length is 1 000 mm, the cutted surface roughness Ra≤6.3 μm, position accuracy ±0.1 mm/m, and oxygen pressure ≤0.15 MPa. |
