Shaping and forming of fused silica
Typically, fused silica is cut using band and wire saws as well as chop saws. The cut loss and surface quality depends on the machine and the feed speed. It is also possible to cut fused silica using CO2-Lasers or a water jet machine. While a laser produces flame-glazed surfaces, a water jet produces a rougher surface.
