The width of fiberglass mesh is fixed in the production process, then it will become rolls. Manufacturers sell products of different widths, so you just need to purchase meshes according to the procurement requirements.. If you do not need special width, you can customize it at the factory. If it has to be processed into rolls of different width, hand saw is suggested because the temerature generated by rapid electric speed won't be lost in a short time. But the high temperature will melt glass, increase resistance, damage saw web, and even burn the circuit.
How thick it is? If it is single-layered, just use scissor.
When grinding, fiberglass will burn easily, thus make cutting machine overload and burn down. And the coking will binded on grinding wheel, thus causing grinding wheel lose grinding capacity and cutting glass fiber into powder. Use round saw bit instead of steel bit. Then the coking glass fiber will heat and burn down the fiber. So the frictional resistance is very big, and reduces friction force between blade and glass fiber. The main reason of using grinding wheel to cut is that the cutting machine will not be overloaded and damaged.
