This invention relates to the field of optical technology, and discloses a cutting system and method based on Airy beams to achieve precise positioning and flexible position switching of the cutting spot. The system includes: a laser source; a coaxial polarizer, a polarization grating rotation assembly, and a lens; the polarization grating rotation assembly includes a polarization Airy beam generator and a first polarization grating and a second polarization grating that can rotate around the optical axis respectively; and the three are in close contact to separate the incident linearly polarized light into two Airy beams based on optical axis symmetry, and the deflection direction of each outgoing Airy beam changes with the rotation of the first polarization grating and / or the second polarization grating, and each outgoing Airy beam can be regarded as the same exit point; the control host is used to position and switch the position coordinates of the focal points of each Airy beam behind the lens on the fixed focal plane by controlling the rotation angle of the first polarization grating and the second polarization grating, the fixed focal plane being perpendicular to the optical axis and having the object to be cut placed on the cutting stage.

This utility model discloses a diamond wire cutting machine for ultra-long foamed aluminum sheets. The diamond wire cutting machine includes a cutting frame and a foamed aluminum sheet clamp. The cutting frame includes an upper horizontal arm with a horizontal projection plane of U-shape, a lower horizontal arm with a horizontal projection plane of U-shape, and a longitudinal arm. A first guide wheel is installed at the free end of the upper horizontal arm, a second guide wheel is installed at the corner of the upper horizontal arm, a third guide wheel is installed at the connection between the upper horizontal arm and the longitudinal arm, a fourth guide wheel is installed at the free end of the lower horizontal arm facing the first guide wheel, a fifth guide wheel is installed at the corner of the lower horizontal arm facing the second guide wheel, and a sixth guide wheel is installed at the connection between the lower horizontal arm and the longitudinal arm facing the third guide wheel. A ring-shaped diamond wire sequentially passes around the first, second, third, sixth, fifth, and fourth guide wheels. This utility model has strong versatility and is suitable for cutting ultra-long foamed aluminum sheets.
