| Abstract: | The cause of producing "mapping" in the process of end surface by fly-saw is analyzed. By reforming the state of cutting, mending saw, adopting line to line pass design, and improving the state of steel pipe cut etc, the state of cutting by fly-saw is optimized, the defect of "mapping" is controlled and removed. |
