Description

Perfect Crystal Cut Polishing Method

The present invention relates to a cut polishing method of quartz crystals commonly used and used in the jewelry industry, and more particularly, the present invention relates to an oval-shaped polishing cut method among crystal cut polishing methods. Conventional jewelry polishing has been using a polishing method of Brilliant Oval or Step Cut Oval (see Fig. 3), and as a work process sticks (Dop) to help gemstones in the grinder (Fig. 4) Stick to the end of the stick (D) and attach it to the Dop Chuk Spindle (D1) of the hand piece (H) to adjust the protractor and index gear (I). The polished surface can be obtained by obtaining the polished surface and rotating the polishing plate to adjust each part of the machine. After polishing one side, the help stick is moved to obtain another side. This operation is to be repeated until the correct angle and grinding. In addition, by moving the dop stick up and down and changing the angle (Angle), you can get a complete shape of the whole part of the gemstone, and the polishing process is to go through the same process. Brilliant Oval has a polished polished surface and is polished close to the crystal structure of crystal. The brilliant oval has the best glare, dispersion and refractive index. It is inadequate to polish gems with the same number of facets and suffers from the loss of cutting and polishing gemstones up to 40%. In addition, step cut ovals with the same number of facets have a higher refractive index than brilliant ovals. It is less effective in scattering, requires a lot of precision in the process, and has a lot of time due to the complexity of the process, and the loss of the size and weight of gemstones can be as high as 30-40%. The following is a conventional step cut oval-shaped polishing method sequence for the purpose of understanding the present invention is shown in Figure 3, the polishing angle and index group number is the same as Figure 3 (a, b, c), the gloss is polished Is the same as

Step Cut Oval (Gold Angle and Index Number)

The index gear shown in the above chart refers to a gear wheel that moves the dove pressure, and “62-2” is an index gear number that can be ground at a 42 degree angle, and 34-30 is also an index gear that can be ground at a 42 degree angle. As a number, this means that any four faces can be polished in the direction (step cut or brilliant polishing method) to polish the gemstone at a 42 degree angle.

In addition, the primary and secondary in the chart refers to the order of polishing and adjusting the index gear as described above, the angle of the chart refers to the angle of the protractor of the index machine, 62-2, 34-30 (four sides) of the table ) Refers to the polished surface obtained by fitting the index gear.

In detail, the grinding surface obtained from the first to 42 degree angles is all four faces 62, 2, 34, and 30, and the number shown on the face refers to the index gear number. . In particular, "-" in 62-2 refers to the plane of symmetry, and four sides are represented by "62-2, 34-30".

As shown in Fig. 3, (1) the primary polishing protractor of the crown face is set to 42 ° angle, the indexer is matched to the number 62, the polygon polished surface at 42 ° angle is obtained, and then the indexer is matched to the number 2, and the A polished surface is obtained, and 34 and 30 degrees are matched with the number of the indexing machine in the same manner as above, and then a polished surface is obtained. Match the indexer number 60 and 4, 33 and 28 with the protractor at 41 ° angle for secondary polishing, obtain a polygon polished surface with 41 ° angle, and indexer number 56 and 8 at 40 ° angle for tertiary polishing , Match 40 and 24, obtain a polished polygonal surface at 40 ° angle, adjust the protractor to the 39 ° angle for the fourth round, match the indexers to numbers 50, 46, 14 and 18, and obtain a polygonal polished surface at 39 ° angle. The table side lower surface T1 of 3 (a) is obtained. In order to obtain the upper girdle side upper surface G3 of FIG. 3 (a) again, the above-mentioned girdle side upper portion of FIG. 3 (a) was polished in the same manner as described above over the fifth, sixth, seventh and eighth orders. Get the noodles.

(2) The pavilion side obtained 16 girder side girdle side (G4) in 1st-4th stages and 16 tier 12 lower girder side top surface (G5) in 5th-8th stages. 16 surfaces of the curet side upper surface C2 are obtained, and 16 surfaces of polygonal polishing surface C1 associated with the curet are obtained in the 13th to 16th order, but such a pavilion surface has the same angle as the crown surface polishing. The work stop time is large due to the adjustment of the and the jewelry itself requires a precise angle in terms of weight and size, so that the loss due to cutting and polishing of the gemstone has to be taken.

As in the above method, in order to polish the next sequence, stop the polishing machine, readjust the protractor and indexer and repeat this process according to the sequence to polish the crown face and pavilion face and work the polishing work in the same repeating order. It is.

Therefore, in the conventional method, although the angle can be obtained by dividing the angle to obtain more polished surface during polishing and polishing, the adjustment time of the help stick is longer and the time lost due to the stop operation for the adjustment. Higher efficiency, less work and polishing of crown face and pavilion face at many angles at the stage of work process, which leads to unnecessary process and loss of time. The high value-added gemstones due to this breakage and imbalance caused difficulties in calculating the price and gemstone grade, resulting in 40% of the gemstones lost by cutting and polishing, and having the disadvantage of not making the most of the gemstones. As a variation of the above two methods, there are many gemstone polishing techniques, but there are no polishing techniques that match the material, weight, and size of gemstones. Influenced.

The crystal is a gem that is closest to the diamond crystal structure, and is polished by Step Cut, Brilliant Cut, or Mixed Cut. There are various polishing forms, but the present invention is an Oval. As a type of quartz polishing cut method, it uses a grinding method of Brilliant Oval or Step Cut Oval (see Fig. 3) as in the conventional Oval type gem polishing. The polishing process that requires gemstones requires reworking the gemstones when a small error occurs. Especially, because of the angular work, it is impossible to utilize the deformation and gemstones as a whole if the error is not corrected at all. Is brought about. Accordingly, an object of the present invention is to provide a brilliant crystal polishing method that reduces the work process and loss of gemstones than the conventional oval-shaped quartz polishing method, and has the same brightness as the brilliant cut crystal. Its purpose is to provide beautiful brilliant cut crystals with high reflectivity of the crown and irregular pavilion faces.

The present invention is a crown and a curet having a table (T) and a bezel (B), a table side star (S), and an upper girdle (G1). (C) and (C) a modified pavilion main surface (M), a lower girdle (G2), and a pavilion surface with a paving plane (Pavilion) with a polished surface of the modified polygon, It is composed of a girdle (G) surface in connection with the two surfaces. The following shows the method of polishing order as a perfect crystal polishing method of the embodiment of the present invention. The polishing angle and index number are as shown in FIG. 1, and the gloss is the same as that of polishing.

Perfect correction (abrasion angle and indexer number)

(1) The perfect crystal polishing method, unlike the conventional polishing method, polishes at one angle, so as to reduce the temporal loss due to the variation of the angle, as shown in FIG. ° At the angle, match the indexer number as shown in the table above to obtain the bezel plane (B) on the 16th surface, and the star on the 4th side of the star surface (S) at 30 ° after the second polishing and 30 ° at the 30 ° after the third grinding Shape of polygonal polished surface of 12 surfaces is obtained and the 16 surfaces of the upper girdle surface G1 are polished by 34 °, 37 ° and 41 ° angles during 4th, 5th and 6th polishing. Get the same face

(2) As shown in Fig. 1 (b) (c), the pavilion was polished at 16 ° and the lower girdle surface (G2) was first polished at 46 °. ° At each angle, obtain the main surface (M) according to the numbers listed in the 2nd and 3rd tables of the above table, and then grind it with a deformed polygon on the same line as the curet according to the following procedure. It is a new fashion cut polishing method that breaks the uniform refractive index and dispersion as seen in the conventional polishing method by taking a completely new type of polishing method that leads to the curet C through different refractive indices and dispersions.

The above-mentioned perfect quartz polishing method is carried out at one angle, which simplifies the working process unlike the conventional method, resulting in a shortening of the working process time, and cutting the angle of the crown surface close to the size of the gemstone, resulting in high price. Reduce the loss of gemstones.

In jewel polishing, the pavilion's polishing angle is the jewel fragments produced when cutting the gemstone, the size of the jewel, the angle of the bottom of the jewel that influences the scattering or refraction of the jewel. Has a profound effect.

The perfect embroidered special cut of the present invention can grind the weight and size of the gemstone with the utilization of nearly 80%, and in the process, it is possible to reduce the time loss of the angular polishing by minimizing the polishing angle, thereby having high jewels. The added value can be further maximized.

In particular, in the conventional polishing method, the crown surface is polished in the 8th order and the pavilion surface in the 16th order, whereas the present invention is the 6th crown surface and the pavilion surface is 12th order. Due to the large number of inventions, the working process is shortened (the conventional crown surface polishing method takes a lot of angle adjustment time, whereas the crown surface of the present invention has no 7,8th process and the pavilion surface can also be shortened from 16th to 12th order). In the conventional polishing method, the angle of polishing based on the vertical surface of the gemstone is an acute angle, whereas the present invention provides a loss of gemstone because the angle of polishing based on the vertical surface of the gemstone is an obtuse angle than the conventional polishing method. There is little advantage. Therefore, while the conventional polishing method utilizes 60 to 70% of the weight and size, the present invention has a utilization rate of 80% because the weight and size of the gemstone loss is small according to the obtuse angle.

In addition, the total reflection rate is also obtuse, which increases the total reflection rate.

Therefore, the perfect cut special cut, with the polishing angle different from the conventional method, minimizes the polishing angle and minimizes the dispersion of light, reflectance and size of the new type of cut. Eggplant is a polishing technique that can enhance the rareness and splendor of the gemstone to maximize the characteristics and properties of gemstones.It also maximizes the dispersion of light due to the curet and increases the total reflectance of the crystal. It gives an optical illusion effect on refractive index and dispersion degree, and the refractive index and dispersion degree give the same effect as the existing brilliant cut, giving a lot of quality of jewelry and external weight of jewelry. There is an effect that can help you see the effect.

In particular, in the perfect crystal polishing method, when the crown is polished, the bezel surface and the star surface are divided into two angles instead of one angle to increase the unique refractive index of each angle, thereby amplifying the scattering of light and the surface of the pavilion. Seeks a fashion cut shape that includes a deformed main face and a lower girdle face, rather than a conventional brilliant cut and step cut method, so that the curlet portion of the conventional brilliant cut and step cut diffuses light at a single point. In order to increase the dispersion of the crystal, the fashion cut has the effect of maximizing the crystal's Brilliance by using irregular polygons to maximize the refractive index and dispersion of the crystal through optical illusion. In addition, it improves the multicolor and the highest quality and material quality by the scattering degree and brilliantness which the original jewelry has In that allows you to be polished to create high added value through a combination of highly polished ways of modifying the price of the precious metal it will be useful inventions that effect.
