Today, I will give you a brief introduction to the manufacturing process of glass beads. I hope you can understand it.  First, blank making: Various spherical blanks are made by various techniques. Second, rough grinding: Put the spherical blank into the two concentric ring-shaped grinding discs with the same size on the upper and lower sides, and the cross-section of triangular grinding grooves that match the blank size, and add oil and rough abrasive; the upper grinding disc rotates, The lower grinding disc does not move. The above ball grinding machine is called a coarse grinding machine. Third, cleaning: every time the rough grinding is completed, the oil and coarse abrasive residues sticking to the surface of the ball should be washed.    Fourth, fine grinding: put the rough-grinded blank into the fine mill; add low-viscosity oil and fine Abrasive, grinding to standard size;    fifth, polishing: the process is similar to rough grinding and fine grinding.   As for craft-grade crystal balls and high-precision top products, they also need to be polished with silk and fur.
