First, popularize the process of bead processing: the process of batch bead processing of natural gemstones begins with raw materials. If the size of raw materials exceeds 15cm, the large cutting table (commonly known as water cutting machine, water saw) cuts the stone and reuses it. Small cutting machine (hand-cutting machine) slicing, cutting and cutting squares, cut squares and then chamfering by chamfering machine, then using medium-disc machine (single-drive grinding machine or double-drive grinding machine) Grinding round, and finally using a vortex bead machine (fine grinding ball machine) to finish the beads, and finally the hole and polishing (this order of punching and polishing is exquisite, this will be mentioned later). If the bead is punched, the ultrasonic multi-needle puncher is used. The 8mm bead can be used to make 85 beads at the same time. The smaller the size, the more the polishing is done. The main procedure for all batches of beading is this way. Of course, it is specific to different stones, with different degrees of softness and hardness, stone brittle is not brittle, there is no cracking, etc. The processing details are not the same, and some need to be filled. The glue is optimized to make the stone less prone to cracking during processing. Most of the natural crystal processing is now concentrated in the area of ​​Guangdong. In particular, Haifengketang is famous for its far-reaching stone. The stone that can't be processed outside can be solved here. This is the advantage of Ketang.
The first step in the processing of the bead: If you have a relatively large material, you must first cut the large material into small pieces first. The size of the large cutting table is 60 cm, which is 24 inches. There are also direct 80 cm, 1 m, 1.5 m.
In fact, in the processing of the whole bead, it seems that the simplest cutting process is the most difficult part. The layman may not know that people who have done high-end goods such as tourmaline know that the material must be understood. Leave the good stay, bad or cracked cut, see here, the ball blank block is ready, and then chamfering can be done.

The chamfering machine naturally uses the chamfering machine. The principle of chamfering processing is relatively simple. It is to put hundreds of billet blanks in the drum at the same time. The inner wall of the cylinder is wrapped with rubber skin and driven by a high-speed rotating disc. The billet is rolled and rolled in the drum. Under the interaction between the stone and the sand disc, the stone and the stone, the purpose of chamfering and chamfering is gradually realized. If the time is long enough, the pebbles can be so polished.
Double-drive beading machine, the double-drive beading machine is more complicated in structure than the single-drive beading machine. The grinding disc used is similar to the single-drive grinding bead, but the groove of the grinding disc is more than that of the single-drive beading machine. The bead plate should be deeper (the focus of the ball can be rounded more). In general, the double-drive beading machine is an enhanced version of the single-drive beading machine, an upgraded version, and a double-drive beading machine. It is driven by the upper and lower motors during work. This purpose can double the processing efficiency of the ball once more. The single-drive beading machine has to grind for 10 minutes. The double-drive beading machine only takes 5 minutes or even 4 minutes. Or less. And the most important advantage is that the dual-drive beading machine is much larger than the single-drive beading machine, the size is all-you-can-eat, soft and hard. Soft materials such as amber and turquoise have long been used when processing these soft materials. With this dual-drive beading machine, small beads can be processed.
