모모Rough Polishingaccording to jewelry Industry veterans said that its development will still be in a good situation. https://tonglinring.com/
모모
모모1, First of all, the rough toss. Rough polishing is to throw away the file marks, pliers marks, drill marks, burrs and the black oxide layer left by welding on the surface of the jewelry metal bracket, and try to throw the jewelry metal bracket flat and coordinated, so that the arc is smooth and the lines are smooth. But also can not be too hard, polishing too hard, such as in the jewelry bracket surface left a depression will be difficult to restore its appearance. Rough casting is the basis of medium casting and fine casting. If it fails to meet the requirements, it will affect the later polishing and directly affect the quality of jewelry.

모모2. Then start polishing motor, rotate polishing brush (Zong brush) by motor shaft rotation force, brush tightening will be coarse sweeping agent C green wax block (containing chromium oxide) daub on the brush, you can polish.

모모3. The brush is mainly used to polish the mesa of the inlaid jewelry, the main and auxiliary stone edging, the gap of the decorative decoration and the outside of the ring, but also to polish the reverse side of the jewelry. In the process of operation, the first thing to pay attention to is to evenly polish the wax to the brush, polishing force should be appropriate, not too much force and cause jewelry deformation, claw, loose claw, and even stone phenomenon, also can not polish is not in place and still have residual file marks, scratches, etc. All jewelry should be rough polished again, polishing is not obvious enough to repeat polishing.

모모4. If polishing the inlaid ring, the inner ring of the ring should be polished with a velvet rod, and the appropriate velvet rod should be selected according to the needs. Green polishing wax must be applied to the ring velvet core before polishing. When throwing, pay attention to the contact surface of the velvet mandrel and ring, that is, the ring can not be set into the velvet mandrel too deep, and keep the polishing contact surface is 1/3 of the inner circle arc. Polishing Angle surface is too small, the working efficiency is low; If the contact surface is too large, it is very inconvenient to change the polishing position. Moreover, due to the large friction resistance, it is difficult to hold the jewelry to be polished, and it is easy to cause the polished jewelry to fly out and damage the shape of the gem ring surface or jewelry.

모모5, rough polishing should pay attention to the brush and cloth wheel waxing, but a waxing can not be daub too much, to avoid polishing wax after the heat to melt it covered on the surface of the jewelry, and cover the jewelry surface traces and pockmarks, which will affect the quality of rough polishing jewelry, and bring difficulties to fine polishing, and even lead to rough polishing again.
모모
모모6, Polishing operator polishing techniques will also affect the quality of polishing, polishing operation is not correct, it is impossible to throw good jewelry. Generally speaking, when polishing, try to make the jewelry parallel to the polishing cloth wheel, hold the jewelry tightly with both hands and move along the cloth wheel from the top down. Polishing must be done evenly all parts of the jewelry at once, each part must be thrown in place. The polishing technique is not correct, and the polished jewelry is easy to be flicked off the hand on the high-speed polishing wheel, which is very easy to cause damage to the gem ring surface, deformation and fracture of the metal bracket. If the polished jewelry is small in size (such as chest pendants and ear studs), you can prepare a hook made of wire. Keep the polished jewelry with your left hand, and avoid skipping polishing and uneven weight of force during polishing. If there is a jumping phenomenon, it may be that the polishing wheel is not on the axis, it may also be that the polishing cloth wheel is not round, it is more likely to be the gesture problem, find out the reason, it is good to solve the problem.

모모7, Some of the more difficult polishing of alloy jewelry, due to the metal toughness of jewelry in the soft metal cast light retention phenomenon, not easy to throw bright metal surface, can only be repeatedly polished to meet the requirements, such as platinum jewelry as far as possible polishing, polishing method and rough polishing is basically the same, still with a brush and yellow cloth wheel polishing, polishing wax is different, It mainly uses white polishing wax with fine particle size (it is an oxide containing aluminum). Medium polishing is to operate in accordance with the rough polishing method, the jewelry from beginning to end again.

모모Fine Polishing

모모8, Any jewelry after rough polishing must be fine, so as to make the metal jewelry surface finish stronger, fine polishing is further fine polishing on the basis of rough and medium polishing, make the jewelry surface more flat, smooth, to achieve the effect of mirror reflection. But its polishing friction contact surface is small, polishing not only the force should be small and uniform, and the surface of the jewelry must be completely polished again, the specific method is to use a fine white cloth wheel with red polishing wax, polishing the front of the jewelry, and then polishing the side of the jewelry, the corner. If the ring is polished, it should be polished with red wax on the ring velvet core rod. Then, polish the front of the ring on the floral shoulder, and finally polish the sides and outer ring of the jewelry.

모모9, The jewelry after rough polishing, polishing and fine polishing 3 times, it should be said that the surface of the jewelry can reach the degree of smooth as a mirror. But sometimes because the grinding is too rough, there are still large file marks and scratches on the surface of the jewelry. It몶s very difficult to remove it through the polishing procedure. There is also the polishing process will row cover in the jewelry surface under the pitting spot grinding out, which not only affects the finish of the jewelry but also affects the quality of the jewelry, the situation must be trimmed, the jewelry on the trace file mark to use the hanging grinder to sweep the needle sandpaper to polish. Jewelry surface pitting spot must be repaired welding, grinding flat before polishing.몪몪
