Rough grinding is the first grinding process used to shape the edges of glass after cutting. A table router equipped with a diamond bit is used to rough-grind the glass and precisely shape the edges. A coarse-grit bit with a low grit number is used to quickly remove large irregularities and chips.
During rough grinding, use water (wet grinding) to cool the surface as you grind. Grinding without water causes glass dust to scatter and can cause the bit to seize up. Use a splash guard during grinding and take care to prevent water containing grinding dust from splashing onto the surrounding area. Please dispose of the wastewater generated after grinding properly.

After rough grinding, proceed to intermediate grinding and then polishing, gradually increasing the grit size, to ultimately achieve a smooth surface.
