There are currently three common diamond cutting methods:
, a diamond drilling along the diamond itself. , the diamonds are used to apply diamond powder on the grinding plate to see the diamond powder to see the diamond. . Because the main component of the diamond is C, the diamond is cut through the laser cutting by laser cutting. Pucting information: For bright cutting, the standard cutting method is 57 mask cutting. The titles as follows, please refer to the 4C standard of diamonds:
crown (CROWN): The parts above the diamond are called the crown, including 1 desktop, 8 stars, 8 stars, Star Facet, 8 kite noodles, and 16 upper girdle faces, a total of 33 cutting surfaces Girdle is the widest part of the diamond, which is also a segmentation of diamonds. At the junction of the crown and the lower part of the pavilion, the waist circumference is where the jewelry is inlaid to fix the diamond. The part below the Pavilion diamond is called the pavilion, which is from below the waist to the tip of the diamond. Including 16 waist planes, 8 pavilions, Pavilion Facet, and 1 bottom of the bottom of the bottom, because the diamond does not have the sharp bottom surface, so there is no pointed sharp surface. There are only 24 cutting surfaces on the diamond pavilion on the bottom surface, and the total number of cut surfaces is 57 cutting surfaces. The bright cutting method of bright cutting For diamonds of the same size, in addition to using the inlaid method to highlight its own classic processing process, it also gradually uses a unique cutting method to chapters. Show your own cutting skills. Novelty cutting methods can apply for patents. However, it is impossible to say that it is novel, but it is the fusion of some of the above cutting methods, and the requirements for cutting machines are very high.

1. Diamond hair wiring line, showing that the drilling blank should be divided along this line. 2. Put the diamond billet of the schemes on the suitcase and use a saw tablet (a phosphorus and copper cylinder with diamond powder and lubricant on the edge) to rotate at a high speed to see the diamond can be seen open the diamonds. Essence 3. Modern introduction of laser technology cut diamonds, greatly improving the processing efficiency of drilling blank. 4. Fix the drilling blank on a high -speed rotating lathe, and then use the diamond on the other arm to form the rotating drill blank. 5. Put the diamond on a cast iron disc with diamond powder and lubricant. The tools used: projector, high -level, microscope, laser cutting machine, and cure The cutting of the expansion data diamond is mainly two parts. Large pieces are divided into small pieces, and small pieces are cut into finished products. In fact, the development of cutting is accompanied by industrial technology, from the increase in the number of raw materials to the increasing cycle of science and technology. Prior to the industrial revolution, the shallowness of diamonds was mainly based on the main care. Later, due to the increase in quantity and the development of science and technology, there was a current type. The main ways to divide the drilling diamonds, one is split, and the other is grinding. Most of them are split, such high -risk ways. Now choose a suitable angle on the treasure, grind a groove, the chisel is accurate, knock. If perfect, it will be cracking into a few large pieces according to expectations. If it is not good, it will become many small pieces. For grinding, it is rarely used, because the previous tools are not as fine as the present, the grinding requirements themselves are positive, and the loss of the grinding itself is great, which is far less reasonable than the split. But the level of splitting is extremely high. There are not much to use now, high risk. Laser also needs to follow the explanation, but it is obviously much safer than this way.

Modern laser uses the method of cutting diamonds, and even after the diamonds that have just been mined have no radiation, gems have undergone hundreds of millions of years of crustal changes. Its radioactivity has long become harmful. Traditional diamond cutting has the following steps:
. Line is also called marking, which is marked on the surface of the diamond. This is the first step of diamond cutting. First, check the drilling blank and mark the surface of the diamond. People who do this work have rich experience and proficient in processing technology. The threading staff must pay attention to two points: not only try to maintain the original weight, but also minimize the internal content. It divisions: splitting and sawing cutting. The cutter puts the threaded drill billet on the suit, and then cuts a delant along the segmentation line with another diamond, then puts the knife on the dentan, and stubs with his hand on the split knife with his hand on the split knife. In a suitable force, the diamond will be split in half or more along the texture direction. This cutting is to fix the diamond on the clip, and the saw plate is rotated at a high speed to see the diamond. Modern laser technology introduces diamond cutting, which greatly improves the processing efficiency of drilling. Plobe, polishing. On a cast iron disc with diamond powder and lubricating oil, the car grinds all the petals (aspect) to make the diamond emit a seductive glory. The grinding process is usually to make 8 large noodles at the bottom, and then make 16 aspects. With a sharp bottom, a total of 25 aspects, and thus extending the triangular noodles, the kite and the waist face, a total of 33 face -to -face. The cutting standard. Although round diamonds are the most common cutting methods in the market, and sometimes it feels a bit monotonous, after all, the round diamond is the most popular shape in all kinds of carcass, so it is best to be a round diamond. This information: Diamond refers to diamonds that have been picked up. Vajra is a natural mineral and the rough of diamonds. To put it simply, diamonds are a monomer crystal composed of carbon elements under high pressure and high temperature conditions of the earth. The beautiful and rare diamond is a symbol of love and loyalty, and it represents eternal love.
Change from the cutting process from the rough drill to a round processing diamond usually requires the following 5 steps: splitting, sawing cutting, coarse grinding, cross -cutting and multi -face cutting. 1, split point This job is to split diamond blanks into two. What to do is to open a slot on the blank, then place a piece of rigid in the slot, and then give a crispy blow to the rough. The blank is divided into two pieces. The purpose of this is to enable the rough to obtain the shape that is suitable for sawing or roughly grinding, while eliminating factors such as cracks and impurities affecting diamond value. The split diamond is actually similar to the wood. It is easier to turn the big wood into a small split firewood along the wood texture, and it seems not easy to split from the vertical texture. As far as octagonal diamond is concerned, it has four solutions that paid parallel to its eight crystals. 2, sawing This This process is to drill the blank in the non -ruling direction. Compared with splitting, the advantage of sawing is that the top of diamonds can be kept at the same time as diamond. The tools that complete this task include automatic sawing and laser sawing system. Pay attention to the internal stress of diamond during work. It may cause diamond rupture when sawing, so the use of polarizers at this time is essential. It takes about 2 months to complete a sawn cut of a 300 -carat rough diamond. Octopus, duodenang and cube diamonds are very suitable for this work. There are many types of sawing tools: there are plates and laser, there are automatic and manual ones. 3, coarsely grind The purpose of this step is to grind the diamond blank to grind a rough outline according to the expected finished product shape, which is the preparation stage in front of the carved. The operator is preliminarily prepared for subsequent work by removing excess materials and the waist that is perpendicular to the table. This task is completed by a coarse grinding machine, and we can see it as a precise mechanical lathe. The rough drill billet is fixed to the front end of the core axis of the lathe. What the processor must do is to carefully rub the diamond with another diamond fixed on the grinding stick. Round and start to approach the bright and round double cone outline. 4, cross -cutting This start to process diamonds. Generally, the cutting of a bright diamond will be completed by different people: first, the cross -cutter (responsible for the countertop, the four main faces of the crown and the pavilion), or it may be the 8/8 cut The grinding division, and then the multi -faceted grinder took over to complete the remaining work. The diamonds that need to be face -to -face are installed on the pliers we call it "DOP", and work with the pliers is a steel plate with sticky diamond powder. Between 000 rpm. We sometimes use the disk of "Wet", because there are diamond powder and oil mixtures on it. 5, multi -faceted grinding This process is to complete all the remaining face of cross -cutting without processing, including the star surface and the upper and lower waist, and in the special area of the working plate, Polish diamonds.

The world four major diamond cutting centers . Belgium Antwerp Antwerp processed diamonds that account for one -third of the world, from the middle of the 15th century Start becoming the world's "diamond capital". At present, more than 8,000 skilled cutting technicians and more than 300 powerful diamond processing plants are still concentrated here. Due to the improvement of European labor costs, Antwerp is now processed with larger diamonds. The diamonds processed in Belgium include round diamonds and various fancy diamonds. The size is available from 1 point to 10 carats. . Tel Aviv, Israel Traviv is famous for his fancy work. 40%of the global diamond jewelry market and 70%of fancy diamonds are from this. Mainly. The processing level is uneven, and traditional tools are often used. The Israeli cutting is not the same as before, the polishing is very good, the diamond looks bright, and at the same time they retain the original crystal surface, so diamonds are sometimes not just 57 sides (therefore, the approach is more flexible, it can increase the cost -effectiveness of diamonds) Essence . New York, USA The New York, USA is a world -renowned large diamond cutting center. There are more than 400 skilled cutters and about 2,000 diamond merchants. Due to the expensive labor, the main processing large drills are mainly large diamonds of 5 carats. It automatically circular machines that process diamonds in the United States are mainly introduced to Israel. There are 58 noodles in the American -cut circular diamond. Symmetry is not as good as Belgium. . Mumbai, India India and Mumbai are the emerging diamond cutting center. Their cutting has its own system to meet the needs of various buyers. Due to the low cost of labor, most of the diamonds in India's cutting diamonds are about 0.20 carat diamonds. The quality is poor and the cutting process is relatively average. The most significant feature is that the waistline is thick and the crown surface is narrow.
1. Check the drill blank first and mark the surface of the diamond. 2. Put the schemes of the drilling billet on the suites, then cut a dentan along the segmentation line with another diamond, and then put the square knife on the deresses. Tap with a suitable force, the diamond will be split in half or more along the texture direction. 3. Most diamonds are not suitable for splitting. At this time, you need to cut it with a saw. Since the diamond color can cut the diamond, the saw tablet is a phosphorus and copper cylinder with diamond powder and lubricant on the edge. Essence Diamonds are fixed on the clip, and the diamond can be seen at a high speed to see the diamond. Now the laser technology is introduced into diamond cutting, which greatly improves the processing efficiency of drilling. The expansion data is cut This refers to the geometric shape and arrangement of various petals of the finished nude diamond. The cutting is divided into three items of cutting ratio, polishing, and modification. Each item has five levels, from high to low in order is Excellent, very good, good, fair, poor. Generally, diamonds are cut in standard round diamonds. The top -level -cut stones can reach the closest percentage of light reflexes, that is, three E x (Excellent) cutting, but this cutting price is slightly more expensive, because its income rate is relatively low, the rate of income rate is relatively low, the rate of income rate is relatively low, the rate of income rate is relatively low, and its income rate is relatively low. It is not about 5%higher than the price of the three EX cuts, but the color of the three EX stones is definitely the most gorgeous. We several other common cutting forms include circular emerald, oval, pear-shaped, princess square, pillow-shaped, heart-shaped, eight-hearted eight arrows-Cupidcocye, etc. The cutting standards have certain differences in each country. The Chinese inspection has divided the cutting diamonds into three levels: good, good, and average. Reference materials: Baidu Encyclopedia-Diamond
