Generally, the granite used for gravestones mainly includes Shanxi black, white marble, sesame black, sesame white, Luoyuan red, and imported Indian red and tan. Stone processing: the mined stone is transported to the factory for processing through logistics. According to the drawing size of the tombstone, the stone of the foundation parts needed by the tombstone is cut with a diamond disc cutter. According to the specific size of the tombstone drawing, cut the stone from the big block with a small cutter. In this way, all the components of a whole tombstone have been cut. After stone processing and cutting, it is generally block and strip. It is necessary to use drilling machine and other equipment to process arcs with different curvature radii, grooves on the tombstone surface and various shapes of the tombstone end face, so that their outlines are basically shaped. Processing of tombstone stone: Grind the stone with basic outline by hand, and then grind other small end faces and curved surfaces by small hand machine, so that the basic shape of tombstone is basically fixed.
