Silver

The jewelry inlaid with gemstones is very rough before the metal surface is not polished. No matter how delicate grinding is grinding during the grinding stones, there will be some subtle marks and polished rubbing marks on the surface of the jewelry. The drill marks on the edge of the hole, the shovel marks on the side of the trim, the clamp marks left by the fixture, and the small welding scars left by the welding residue. At present, 18K gold, 14K and platinum jewelry such as jewelry inlaid jewelry are polished by mechanical cloth wheels. This is the most important part of the surface treatment process of jewelry. The surface of the jewelry after polishing should be extremely bright, giving people a glorious beauty. Of course, mechanical polishing has certain skills. It is necessary to be equipped with various cloth wheels and polishing waxes. It is not the longer the polishing time. loss. rn　　一、抛光使用机械与工具品名rn　　抛光机、吊筒打、黄布轮、白布轮、大毛刷、绒芯棒、小毛刷、小白布轮、直毛刷、绿蜡, White wax, red wax, drum machine, small round iron beads, small flying saucers, polished powder, rust -proof powder.
. The roller is polished
The drum machine adds small round iron beads, small flying, agate, polished powder (add a small amount of water) to start grinding and polishing. Jewelry, such as earrings, chest pendants, and uneven lines, necklaces are accompanied by diamonds with many diamonds for grinding and polishing.
. Detailed operation of polishing process
1. First of all, rough throws. Rough polishing is to throw off the soda marks, clamp marks, diamond marks, burrs, and black oxide layers left on the surface of the jewelry metal bracket. Make the lines smooth. However, it is not too large and polished. For example, leaving a depression on the surface of the jewelry bracket will be difficult to restore its appearance. Rough throw is the basis of medium and fine throws. If it is not required, it will affect the later polishing, which will directly affect the quality of the jewelry.
. Then turn on the polishing motor, use the motor axis rotation force to rotate with polished bristles (ancestral brushes), and after the brush is tightened On the brush, you can polish.
3. The brush is mainly polished on the countertops of the inlaid jewelry, the main and auxiliary edge, and the gaps of the flower jewelry, as well as the outside of the ring. During the operation, the first thing to pay attention to is to evenly polish the wax on the brush. The polishing force should be appropriate. It cannot cause excessive force to cause jewelry deformation, paw, loose claws, or even stones. There are still residual marks, abrasions, etc. All jewelry should be polished thickly, and the polishing should be repeatedly polished.
4. If you polish the ring, you should also use the inner ring of the polished rings with a pill core rod. Select the appropriate velvet rod as required. Before polishing, you must apply a green polished wax to the rings. When throwing, pay attention to the contact surface of the villuk core and ring, that is, the ring cannot be put in the pill core stick too deep, and keep the polishing contact surface of 1/3 of the inner ring arc. The polishing angle surface is too small, and the work efficiency is low; the contact surface is too large, and it is very inconvenient to change the polishing level. Moreover, due to the large friction resistance, it is difficult to get stable and polished. The shape of the ring or jewelry.
5. Pay attention to the bristles and cloth wheel wax when coarse polishing, but you cannot apply too much on the wax to avoid the polishing wax rubbing and heat it to melt it on the surface of the jewelry. Signs and hemps, etc., will affect the quality of the thick polishing of jewelry, and bring difficulty to fine polishing, and even lead to re -throwing.
6. The polishing method of polishing operator will also affect the polishing quality. If the polishing operation method is incorrect, it is impossible to throw jewelry. Generally speaking, when polishing, try to make the jewelry parallel with the polished cloth wheels, hold the jewelry with both hands and move the direction of the cloth wheel from top to bottom. Polishing must uniformly complete the nationwide of the jewelry at one time, and each part must be thrown in place. The polishing method is incorrect, and the polished jewelry is easily taken off by bombing on the polishing wheel of high -speed flying. For example, the polished jewelry is small (such as chest pendant and earrings), you can prepare a hook made of a metal wire, keep the jewelry polishing in the left hand, and prevent jumping polishing and forcelessness when polishing. If there is a jumping phenomenon, it may be that the polishing wheel is not in the axis heart, or the polishing cloth wheel may not be round. It is more likely to be a gesture problem. Finding the reason is to solve the problem.
7. Some of the more difficult alloy jewelry, because the metal toughness of making jewelry is tough on the soft metal to lit with a stranding phenomenon, it is not easy to throw the metal surface. The jewelry should be polished as much as possible. The method of polishing is basically the same as the rough throw. It still uses the
brushes and yellow cloth wheels to polish. The medium throw is only different. (It is aluminum -containing oxides). Mid -polishing is to operate according to the method of rough polishing, and polishing the jewelry from beginning to end.
8. After any jewelry is thick, it must be polished to make the surface of the metal jewelry more smooth. The fine throw is further polished on the basis of thick and medium throwing, making the surface of the jewelry more flat and smooth, and achieved to achieve the surface of the jewelry. Mirror reflective effect. However, its polishing and rubbing contact surface is small. When polishing, not only is small and uniform, but must be fully polished on the surface of the jewelry. The specific method is to use a fine white cloth and red polishing wax. , Then polish the side of the jewelry, the corner. If you polish the ring, apply red wax on the ring rod on the ring rod to the inner circle of the ring. Then, the positive flower shoulder of the polishing ring finally polished the sides and outer circles of the jewelry.
9. Jewelry jewelry is rough, medium polishing and fine polishing 3 times. It should be said that the surface of the jewelry can reach the level of smoothness. But sometimes because of the rough grinding, there are still large traces and scratches on the surface of the jewelry. It is difficult to remove it by polishing. There is also the tattoos that are drained under the surface of the jewelry during polishing, which not only affects the smoothness of the jewelry but also affects the quality of the jewelry. After scanning sandpaper, then polishing. There is a hemp point on the surface of the jewelry. It must be replenished.
. Quality standards for polishing process
A. Quality inspection criteria for rings finished products
1. Surface smooth mirror, no marks, paddles, no welds, and hemp points.
2. The gem is inlaid firmly, Zhou Zheng is beautiful, and the claws, teeth, and trims should be neat and smooth, and the gemstone is perfect.
3. Model, overall beauty, overall coordination symmetry, clear surface lines, clear layers, outstanding themes, and strong three -dimensional sense.
4. The ring ring is thick and uniform, the width and width change lines are smooth, and the edges of the circle are smooth.
B. Quality inspection criteria for finished finished products:
1. The overall coordination, smooth, numb point, no thorn and sharp corner.
2. The gem is inlaid firm, flat, and Zhou Zheng, keeping the gem intact.
3. The seeds of melon seeds and welding are firmly unchanged.
C. Quality standards for finished earrings:
1. The length of the pins, thickness of the ear insertion meet the production requirements and the welding is firm, and it is moderately moderate with the ear buckle.
2. The pendant of the earrings move forward, the pendant chain has no welding marks, and the overall coordination is beautiful.
D, bracelet, necklace quality standard:
1. The chain rings of bracelets, necklaces are firm welding, hook -free and welded marks; gemstones are inlaid firm, no loose and injury; overall stretching, vertical vertical, vertical vertical The level is consistent.
2. The loosening of the connection is appropriate.
