There are several steps in gem processing:
1. Purchase raw materials (that is, go to a stone store to buy the corresponding stones):
1. Select materials, stone There are several types of materials: the commonly used ones are AB material, B material, C material, and D material. Among them, the larger stones of AB material are used to cut into larger stone embryos, materials B and C are used to cut medium stone embryos, and the smaller stones of D material are used to cut into smaller stone embryos. Just choose the corresponding type of stone and then adjust the color.
2. As for the color, confirm the color according to the required color of the gem. Confirming the color is very complicated and very critical! You have to control the depth yourself... If you have a good color, you can pick up the stone and then slice and dice it.
Second, cutting. The so-called cutting is to first confirm the length of the stone, cut the stone into pieces, and then divide and cut the pieces of stone! Be careful about the size! )
Three, shape. 1. First make the corresponding gemstone model, which is a rough outline model. After the model is completed, load it into the molding machine. Then put the cut stone embryos into the molding machine, and the grinding wheel of the molding machine will polish the stone embryos to the same outline as the model...
Four, polishing and grading Ordinary light polishing and bright polishing. Ordinary polishing means that the quality requirements of the gemstones are not very high. Polishing the polished light means that the quality requirements of the gemstones are a bit high. The so-called polishing is to match the shaped stones with some scraps of different sizes. (crushed sand) are mixed together into a mixing pot (the mixing pot is about the same size as a small shop rice cooker...) and then put some polishing powder for polishing. Generally, it will take 1 day to polish for ordinary polish... If it is bright, polish it 2-3 days. After polishing it is ready for processing!
5. To grind the stone, first stick the ingredients one by one on the iron rods (the iron rods are as thick as chopsticks and only about 10 centimeters in length)! Then insert the iron rod into a grinding stone tool called the octagonal version (hexagonal version). Of course, what I am talking about here is grinding with an octagonal machine... There are also many people who use robots and Taiwanese machines to grind them. I won’t explain it in detail! After inserting the octagonal plate, you start to adjust the position of the machine... The grinding stone always grinds the face of the gem first. To adjust the position, you need to adjust the height of the plate on the machine and adjust it. Then you can start grinding. Then install the sand table and start polishing, that is, take the octagonal plate with the stones inserted and grind it on the sand table... Because the face of the gemstone has several layers and positions, we first need to polish its positions on the sand table. (usually called faceting) After the surface is carved out, you can change the disc... After changing the disc, you can start polishing... that is, just like faceting, hold the octagonal moderator with the stone inserted, one for each slot on the disc. The polishing of the plate is just like that. Of course, polishing still needs something to assist... At the beginning, you need to use fine sandpaper to apply polishing oil and polishing powder on the polishing disk... and then polish... Otherwise, polish This procedure cannot continue.
After the face of the gemstone is thrown, it is time to change one side... Take the stone off the heavy iron rod, change the other side and stick it on the iron rod, and then continue the previous steps... But this time Polishing the bottom is different from polishing the face... Just adjust the position of the machine to the polishing bottom and it's OK... Continue polishing according to different layer positions... One gem will do it This is how it was born! After all the processes are completed... take the stone off the iron rod... and then clean it (you can use low-solubility sulfuric acid or alcohol... It is recommended to use low-solubility sulfuric acid, because sulfuric acid It is much cleaner to clean...and it will be cleaned quickly...nothing else can compare to sulfuric acid...but if you rarely use sulfuric acid, it is better to clean other things...because sulfuric acid is used Cleaning is not safe! If you are not careful when washing with sulfuric acid, you will wear out all the hard work...
After cleaning, you can take it for quality inspection!
Sales:
General manufacturers in Wuzhou provide processing. If you want to process, you can contact the manufacturer and then send it back to the manufacturer.
Artificial gemstones processed in Wuzhou are mainly sold to Thailand, India, the United States and other countries. Among them, Thailand and other ASEAN countries are the main partners of Wuzhou’s artificial gemstone trade.
At present, more than 400 gem dealers in Wuzhou City have established fixed connections with the jewelry markets of Thailand and other ASEAN countries. At the same time, jewelers from the United States, Italy, Mexico, Russia and other countries have also come to Wuzhou to look for business opportunities.
