Guiding system of float glass high-precision cross cutting machine

Disclosed is a guiding system of a float glass high-precision cross cutting machine. The guiding system comprises a linear guide pair guiding system including an upper guide rail and a lower guide rail, which are separately fixed on the upper and lower parts of a side face of a crossbeam. The linear guide pair guiding system includes a plurality of slide blocks, and a cutter head is installed on a plane formed by three slide blocks and moves to the right and the left with the plurality of slide blocks along the upper and lower guide rails. The guiding system of the float glass high-precision cross cutting machine is low in installation requirement and high in positioning accuracy. The guiding system can stably operate, bears lateral force, and maintains stable, and is easy to assemble and good in interchangeability. By using the guiding system of the float glass high-precision cross cutting machine, the cutting dimensional accuracy and the cutting quality of glass are greatly improved; the failure rate of glass plates is reduced; and business economic benefits of glass production are obviously improved.
