[0002] In the current laser cutting process of ceramic substrates, although there are a small amount of burrs on the edge of the cut ceramic sheet, the thickness of these burrs is about 100 microns. Despite this, the presence of these burrs still has a certain impact on the dimensional accuracy of the ceramic sheet. In order to ensure that the thickness dimensional accuracy of the ceramic sheet can meet the requirements of ±20 microns, it is necessary to further optimize the cutting process to reduce the generation of burrs and improve the dimensional accuracy. The current grinding process of ceramic sheets is to manually pick up the ceramic sheet, place it on a non-metallic plane, use a metal file to lightly grind the edge of the ceramic, and remove the laser cutting burrs.
