The "turning" and "patching" in jewelry processing are the same process, they just have different names.

Lathing is a craft that uses a professional turning tool to carve patterns on jewelry. The advantage of this craft is that the pattern is very vivid and beautiful. The disadvantage is that if it needs to be renovated, it cannot be highly polished. This will affect the original pattern.

Surface treatment process of precious metal jewelry:

Precious metal jewelry must be surface treated in the final stage of its production to achieve the ideal artistic effect. . There are many surface treatment methods, including: engraving, gold coating, electroplating, turning (milling), sandblasting, etc.

1. Electroplating process. Electroplating process is a processing method for surface coating of precious metal jewelry, such as gold plating for silver jewelry, rhodium plating for platinum jewelry, etc. The main process of jewelry electroplating processing method is: acid and alkali washing - degreasing and polishing - electroplating. The electroplating process can protect the surface color and brightness of precious metal jewelry, giving the jewelry a more beautiful appearance.

2. Gold coating process. The gold coating process is to wrap extremely thin gold foil layer by layer on non-gold ornaments, then heat it, and use tools to firmly press the gold foil on the surface of the ornament. , leaving no seams. Gold-filled jewelry looks like gold jewelry. Gold coating is also a common jewelry surface treatment method.

3. Engraving process. Engraving process is a process of using a chisel knife to manually create patterns on the surface of precious metals with hammers. The patterns can be deep or shallow, uneven and rough.

4. Turning (milling). Using a high-speed rotating diamond milling cutter to carve shiny horizontal and vertical stripes on the surface of the ornament and arrange them into patterns is called turning or milling. . Because the diamond milling cutter is very hard, the milled stripes are smooth and shiny. What we call glittering rings or glittering pendants are made using carving techniques and are very popular among people.

5. Sand blasting, using high pressure to blast fine quartz sand onto the exposed polished metal surface, creating a hazy and soft surface finish.
