The quietly rising diamond wire loop saw

The quietly rising diamond wire loop saw Diamond wire loop saw is a cutting tool that solidifies diamond abrasive particles onto a circular steel wire substrate. The saw wire is circular. When in use, it is generally wound onto several guide wheels for unidirectional circular cutting. During the cutting process, there is no need to reverse direction. The cutting speed is high, the cutting seam is narrow, and the surface of the slice is flat. It can cut large sized [...]
